Can't Boot Into Windows Since Feature Update, Infinite Loop & Restarts

Hi,

I tried updating to the new feature update the other day, and when I came back my PC was stuck in an infinite loop where it restarts, the BIOS splash screen shows, then the screen goes blue and my PC restarts again with no error messages or anything. So I can't get into the Windows environment at all. The windows logo won't even show.

I've put the original windows 10 installation ISO on a USB and managed to boot into that, but nothing I do on there so far has worked. It won't even let me fresh install windows, and wouldn't show the C: drive of my SSD where my windows is installed. I can however get into safe mode through my USB, but idk what else to do. Thanks for help

Cheers

P.S. Someone said that there are reports that the new update changed the file system where windows is installed to RAW and so Windows can't boot - could this be my problem?

Hi framack4,

Welcome to Ten Forums BSOD Crashes and Debugging forum.
What are the status of the computer files?
Had the files been backed up to another drive or to the cloud?
Had a backup image been made?
If you needed to make a clean install (deletes all partitions, makes an unallocated drive, and re-installs the operating system) would you be able to?
What is the status of the drive (had there been any problems or any software tests?)


Perform the following steps:
1) Find a flash drive that you can format ( > or = 8 GB)
2) Create a brand new bootable Windows 10 iso:
Download Windows 10
3) Temporarily modify the BIOS boot order so the USB external HD is on top
4) Boot to the Windows 10 iso.
5) It may take 5 - 10 minutes for the iso to load while viewing the Microsoft Windows icon
6) Select language, time, currency, and keyboard, or click next
7) Click troubleshoot
8) Click system restore (start with the oldest restore point and keep repeating as necessary to the most recent until there are no more restore points) (if system restore fails or if there are no restore points move to the next step)
9) Click startup repair (if startup repair fails move to the next steps)
10) Click command prompt > Administrator: X:\Windows\System32\cmd.exe > X:\Sources> type:

All of these commands are to be typed unless they are in parenthesis:

13) c:
14) dir
15) d:
16) dir
17) diskpart
18) list disk
19) list volume
20) select disk 0
21) list partition

23) detail partition
24) select partition 2
25) detail partition
26) select partition 3
27) detail partition
28) select partition 4
29) detail partition
30) (if there are any more partitions on disk 0 continue in the same fashion)
31) select disk 1
32) list partition
33) exit
34) dism /image:B:\ /cleanup-image /revertpendingactions
(view the result in step #12 for the partition drive letter. Change the letter B to this drive letter)
35) sfc /scannow /offbootdir=B:\ /offwindir=B:\windows
(view the result in step #12 for the partition drive letter. Change the letters B to this drive letter)
36) chkdsk /r B:
(view the result in step #12 for the partition drive letter. Change the letter B to the applicable drive letter)
(This may take many hours and typically displays ETA.)
(reboot as needed)
37) bootrec /fixmbr
38) bootrec /fixboot
39) bootrec /scanos
40) bootrec /rebuildbcd
41) exit
42) (reboot)

If the above repair is successful consider the repair fragile.
Perform the following steps:
1) Backup all files to another drive or to the cloud
2) Make a backup image using Macrium:
Macrium Software | Macrium Reflect Free
3) Save the backup image onto another drive or into the cloud
4) Make a brand new restore point

If the above repairs fail to fix the boot problem please make sure that images are posted of each command and result for additional troubleshooting steps.

Thanks zbook

What are the status of the computer files?

Not sure what you mean

Had the files been backed up to another drive or to the cloud?

The important files are on OneDrive which was active on this PC

Had a backup image been made?

I didn't make a backup

If you needed to make a clean install (deletes all partitions, makes an unallocated drive, and re-installs the operating system) would you be able to?

Yes, if I have to I'm ok with it, but would rather not if possible. Don't want to lose the files on my two 1tb hdds though

What is the status of the drive (had there been any problems or any software tests?)

No problems. I've used lots of benchmarking/software tests in the past and always passed 100%

Kept getting unknown errors when trying to use windows media creation tool but managed to use the original ISO for windows 10 education

System Restore says: To use System Restore, you must specify which Windows installation to restore. Restart this computer, select an operating system, and then select System Restore.

Startup Repair: Started doing some repairs then back into infinite loop of restarts. I hit F8, booted into USB and now I'm getting this error which I can't seem to get past:

Also, I've changed the boot order in BIOS so "removable device" is number 1 but its still trying to boot into the SSD so I have to manually tell it to boot into the USB

When available please post images for the above steps.

I've had the same. Root cause corrupt bootrec.dll after it tried removing a failed update (which failed). Restored to last point prior to Update. Booted okay but Update continued which then failed so back to square one, unable to get past the corrupt file error.

Sorry for above. Posted in wrong forum and errors when trying to edit.

When Windows upgrades were attempted to 1709 or 1803 what were the error messages and code?

Sorry, I left my PC to it while it was updating. When I came back it was continuously restarting and I saw no error code.
