Your name is "Aomei Account"?

What was your W partition for? What is the brand of your PC? Is this a traditional 2.5" SSD, or an M.2 SSD? Have you tried pushing the Fn Key for UEFI Temporary Boot Menu, or UEFI Menu for your brand?

Prior to attempting any further repairs, please use Backupper WinPE USB to make a full disk backup onto an external hard drive. Always have a backup of your data, in case something goes wrong.

After you have created your backup, please unplug all hard drive cables inside your PC, and plug them back in.

Please insert Win11 installation USB, and use the Startup Repair. Becareful not to use the Win Reset, that will cause data loss.

Here is a link to an article for some suggestions on this issue:

cmd >

bootrec /fixmbr

bootrec /fixboot

BCDboot c:\windows (or letter of win partition)

In my experience, although Partition Assistant has many good tools, shrinking the C drive is usually done better by Win Disk Management.

Great free tools by Aomei:

- Your name is "Aomei Account"?
Yes (AomeiAccount), I created this account, because password for old account is stored in unbootable PC
- What was your W partition for?
Important data and all downloaded apps (I change installation path to W:\ProgFiles, or move app folder from "C:\Program Files" and create junction)
- Is this a traditional 2.5" SSD, or an M.2 SSD?
HDD
- Have you tried pushing the Fn Key for UEFI Temporary Boot Menu, or UEFI Menu for your brand?
Not Fn key, but I opened boot menu. I can boot either into GRUB console or Windows 11

Thanks for other info, I will try it, when will create Windows 11 Installation USB

@BrutalMoose2, when I try to execute commands with C: (for example "dir C:", or "cd /d C:"), I always get this error message: 

The Volume Does Not Contain A Recognized File System

> diskpart
> list disk
Disk ###  Size   ...

Disk 0       465 Gb
Disk 1       58 Gb
> list vol
Volume ###   Name    FS         Size
Volume 0                       FAT       62 Mb
Volume 1        C            RAW     1024 Kb
Volume 3        D            FAT32   32 Gb

Where is my W: drive and why C: is 1 Mb? Why there is no volume 2?
How can I fix it?
Please help

After reinstalling Windows (to Windows 10), W: drive appeared with all data (now D), but C: was formatted

Don't use AOMEI Partition Assistant

@AomeiAccount, " I can boot either into GRUB console or Windows 11"---Are there multiple systems on the disk? And, C and W: drive is adjacent. Or, there is another system (Linux?) partition between C and W: drive.
