Hello Fen,
Thanks for reaching out. It sounds like your real worry isn't really Windows 11 itself — it's making sure your mother's files don't get lost while you try to get this PC working again. Let me try to address that first.
- Corrupted files can almost always still be copied off a drive, even if they won't open properly. Corruption usually affects how the file is read, not whether the bytes can be moved. So, getting them onto a USB stick or OneDrive first is realistic, and it removes the risk from anything you do to the PC afterwards.
- Upgrading to Windows 11 won't repair those files — Win11 and Win10 read files the same way, so the upgrade itself isn't going to recover anything that's damaged. If file repair is the goal, that's a separate conversation and depends on the file types.
- On the upgrade itself, a 60GB drive is technically below Windows 11's 64GB minimum, and the 22GB "System Reserved" figure you mentioned looks abnormal (it's usually only a few hundred MB). That combination makes an in-place upgrade unlikely to complete cleanly, and it may also be part of why updates keep failing.
So, the path I'd suggest, in order:
- Copy mom's files (corrupted or not) onto a USB stick or to OneDrive — that way they're safe no matter what.
- Once they're backed up, you have options: a clean install of Windows 11 (follow this guide https://learn.microsoft.com/en-us/answers/questions/2338451/how-to-make-clean-install-of-windows-11-article) which would also fix the weird partition layout, or just staying on Windows 10 if the PC is otherwise fine for her day-to-day use.
- If you want to try recovering the corrupted files themselves, share a few examples of what they are (Word docs, photos, etc.) and we can look at that separately.
