I’ll try to sum up the story and give some background:
- Old Windows system, upgraded 7->8->10, migrated from HDD to NVMe 2-3 years ago.
- At some point a few years ago dual-boot with Fedora (main system now for work, Windows for gaming/music), now on F33.
- BIOS is UEFI, with MBR partitioning for my two NVMe disks (yes, I know, that’s what happens when upgrading in place).
- Windows installation is old but standard, only one drive. Fedora is using LVM (see partitioning below).
- I want to use holiday break to update to F34 and Windows.
- Last Windows 10 upgrade 2021H2 is stuck because of MSR partition than cannot be updated (normaly a size problem, but even with making some room does not solve it), and some complaining about partitioning not supported by EFI.
So what I’d like to do is to clean up things a little bit before/while updating both systems.
Part of this would be to convert MBR to GPT, which will allow getting rid of the MSR partition (and problem) in Windows.
Where I still have doubts is how to proceed best with the dual boot. I have read relevant material for both Fedora and Windows, but I did not find anything meaningful for this situation.
Any advice? Where to do the conversion from, order,…
Here is my main drive:
(First NTFS is MSR, then Windows)
Second drive is only one partition, part of LVM.
