Bootmgr is corrupt, Computer doesn't recognize the Windows 10 Installation USB-Stick and won't start BIOS/show the Key for it

If your cd/dvd drive won't auto open you can manually open it on the drives face there will be a tiny hole where you can insert a sturdy paper clip end or a very, very fine screwdriver, first switch off the power. gently but firmly push the clip end until the tray just starts to open then pull it open fully but gently, drop the disc into the tray close tray then power up your PC.
 
Just came home and it finally worked. How do I access my old Files in Linux Mint?
Edit: just found it out

Finally reinstalling Windows 10 after a hard Day and some Relaxation Time but there is a Problem when I need to select a Partition. I can only install it on the one with 930.9GB (primary) but I assume I won't be able to save any Files then and I'm pretty sure I didn't install it there previously.
Then there's a Partition that has the Type System but I'll better ask to be completely sure before using it. Can I safely delete the Files on it or is there other Stuff too than just the Windows Files?
 
if you get a hirens disk, you can partition however you want to.
you can then also make backups of the allocation table, mbr..what ever you need.

that's the install default, it is changeable.
I make the disk partitioned the way I like before inserting the install disk.
Windows is terrible at partitioning and it never tells you exactly what you need to know, so experience in installing windows thousands of times...makes sure you remember how.
Its also 100% because of windows terrible ability to fix disk damage that windows itself causes, That I ever started using disktools. way back to windows 2.1 pure garbage.
Windows has hibernate and sleep modes.
In MS entire history, these have never worked correctly and windows cannot fix its own damage that it causes by the use of sleep and hibernate.
To a technician, this means if I don't manually repair often, I will be reinstalling within 2 years or less. and/or buying new drives.
you can make your own partition or use the system partition and install the disktools there. then you don't need to do anything for a repair other than run from windows, 5 minutes and its all good to hibernate or sleep again..
or use a usb or anything..its easy with the correct tools

normally your system partition has the mbr and bootmanger. they need to be properly moved before you can delete that partition, or you will be back to square 1 again.

p.s. if I did not say it before, hirens and Bartpe are free.
you could buy the best on the market and it would not get you the abilities you will get from Hirens.

How exactly do I move them? With one of the mentioned free Programs?
Does the mbr and the Boot Manager consist of single Files or do they have multiple Files. Sorry for asking so much. I remember that I've installed Windows 10 a lot but I can't remember that I ever did this. If they need to make such a suicidal OS, they should at least include a Option for it to re-download Files that are damaged or missing 😒
Currently the Partitions look like this (in Case that this is somehow helpful)

Why can't they just let the User decide which Files from the Partition to keep and which should be deleted? 🤦🏻‍♂️
So annoying

I actually use Hirens v10
I have lots of the disks as I have made so many over the years and a few usb flash drives.
I put new HD in pc, boot to hirens, use paragon partition manager, its at least 10 times faster than windows and can actually complete the task before the week is over....
like 10 minutes instead of windows usual fiasco.
I have never had a failed installation this way.
I use partitions for very different reasons though.
In cases like yours, or for my customers, I just use windows install.
let windows do what it want for the install.
boot into hirens, remove all/any extra partitions so there is only 1.
Done.
you can leave the default system partition alone, its on all computers that are used by people like me. control freaks. techs.
Some partition managers can't do it for various reasons, and there are many reasons.
when this happens it usually has lost the bootmgr.
just about any windows install cd will fix in less than 5 minutes.
 
I will not work on a pc's drives without Norton ghost and a hirens disk.
I always make a ghost before I touch any used HD.
then I do what ever needs doing.

from windows beginning it has been a self destructing OS.
It comes with programs for you to run that look for and repairs specific files, that windows itself damages on almost every reboot.
MS knows this.
The hibernate and sleep make errors cascade because, thanks to the flakiness of some file systems combined with bad programming,.
There are pointers in the files created that have always been at the wrong offset once the computer is awakened. so it gets worse every time the pc hibernates or sleeps.
till eventually you cant boot anymore.
its easily fixable, but not by windows.
unless you spend hours running all the little MS fixes that no tech in his right mind would ever do more than once.
Avast scandisk, all windows pc's should come with this. and make an autorun so it can repair all drives upon a reboot via simple yes/no option.
then your drives could go for 5 or 10 years instead of 2.
and a new experience for windows users would be to never have lost ability to boot again unless the HD dies.
if you don't like the idea behind hirens disktools, you can just buy the latest versions from their makers.
but if you have no experience with this, it can cost a lot of time and money to experiment and learn whats good and whats useless.
Hirens gives you older versions that are mostly considered free, no one is bothered by their use.
the HD manufacturers tools on these disks are free to anyone, but a nightmare to collect all the variety of them...they are priceless, very useful.
Even though I have the newest versions, I use my old hirens because it is sooo much faster to use.

But how exactly do I move the mbr and Bootmanager then before. Is this even really necessary? Shouldn't they just be included in the Windows Installation?
I've read that the OEM Partition isn't necessary when you have a Windows 10 Boot Stick anyways but if I would delete the Files from OEM and just try to install it there, I would still have the old System Files on the other Partition 🤔
 
no, that's why I said, just let windows do its thing.
just don't use the system partition for anything yourself.
If you choose to install the tools option in windows, that's where it usually puts it..

and, the easiest way to move it, is to use the repair from the install disk.
its not a problem to leave as is, most computers are this way.

if you want it gone, go to the install disk, delete that partition, then use the repair tool so it can write the mbr to the windows partition, as it will be the only place it can put it now.
 
MBR gets written to the first part of a hdd and is not visible (without a especial editor) or movable - this is necessary for most os as it describes how the disk is laid out and what the disk contains - with win10 this is usualy replaced with GPT

the first partition on the disk is where the boot loader and recovery environment lives, iirc this is not easy to move and will almost always be the first partition, unless youve installed another OS first ie linux or win7

the OEM partition usualy iirc contains the files used to restore windows to factory settings (as it came from the shop) without requiring the recovery media- you can delete this partition if you wish but you will never be able to run a repair without the media. you can delete this partition but its unlikely windows will install on 500mb, iirc windows 64bit requires 20gb minimum

if you want to keep the contents of the main 900gb you need to resize the 900gb partition to make it smaller assuming there is enough free space - to resize the partition you will need to use something like gparted to shrink the space

then when installing windows select the custom option again and select the blank\empty partition and click new and create a partition using all the available free space
then select the new partition and click next - windows should then install to the new partition leaving your files intact - but i would strongly advise backing any files you want to keep first
 
Just came home now again and I'm mad because it seems like the Windows 10 Installation is supposed to automatically replace the old System Files which obviously doesn't work or else it wouldn't claim that there isn't enough Space. Probably also still has the System Files from the Windows 10 Installation before the last one.
I think there was a Folder with the Windows System Files when I started Linux to save my Files. Could I also just delete those Files before reinstalling Windows 10? This would probably be the least complicated Way and I want to finally end this Torture. I definitely won't forget to install that Software that automatically repairs the System once it works again, so I won't need to do this again as long as I have this SSD.
Also can I run the Windows 10 Installation from Linux when I'm using it from the USB Stick (I do currently only have one USB Stick with enough Space for Linux/Windows and this would save me a lot of Time)

if you want windows installed on the 900gb partition then you need to delete all partitions on disk 0, if you want windows to use as much of your disk as possible dont create any partitions - windows creates partitions it needs during install if you want to use 100% of the disk

if you need to keep files on your 900gb partition then you need to make it smaller using gparted

you could try selecting the option Upgrade install keeping files however you will need enough free space on the 900gb partition to install windows

the c:\windows folder? you can delete this if you dont plan on dual booting 2 copies of windows

if your able to access the disk then delete c:\pagefile.sys,, c:\swapfile, c:\hiberfil.sys you will find these files are probably huge and hidden.. not 100% sure if linux follows windows hidden file rules
ofcourse you will need to boot linux to be able to easily delete any of these files\folders - windows wont let you delete itself from within windows

Ok, good. Then I'll try if this works 🙂
Just need to wait until my only big USB Stick has Linux again


if you want windows installed on the 900gb partition then you need to delete all partitions on disk 0, if you want windows to use as much of your disk as possible dont create any partitions
As already said, I would like to install it like it was installed before and not on the 900gb Partition (I assume I couldn't use this Partition for any other Files if I would do this unless I make 2 Partitions out of it?)
 
It sounds like a UEFI problem. My motherboard/BIOS refused to acknowledge the system disk because of the old MBR mode.


...fixed by doing this:

you can try freeing up space but im not 100% sure windows will install to the 900gb partition without wiping the contents, the windows 10 upgrade and keep files only works if you run the upgrade\install from within windows. otherwise the install runs as a new windows install

if you want to install keeping your files you will likely find you need to create a new partition to install to so you will need to shrink the 900gb partition by at least 20gb but i would recommend more than 50gb if you plan on using the new install of windows permanently

Already moved my important Files to a external SSD a few Days ago 👍
 
Linux even gives Access to the System reserved Partition. Is my Assumption right that I can delete everything there except the Boot Folder?
 
Ok, but wasn't it mentioned before that there are 2 Files that need to stay in that Partition?
if your not sure leave everything alone on that partition windows will change those files during install

if you want to split the 900gb partition into smaller chunks then delete the 900gb partition and recreate it as a smaller size ie 100gb for windows 800gb for files

but the best way is to delete every partition, create a 100gb partition for windows and a 800gb partition for files (makesure you select the 100gb partition before clicking next)- windows will (or should) automatically resize and crate the 100mb and 500mb partitions automatically during install
