hi! I keep getting error 0x80004005 when installing 24h2 and 25h2 which I didn't get when updating to 23H2.
After some digging I think it might be due to the startup partition not being on the primary (SSD) disk, but rather on an old HDD which is only used for storage.
When I try to do a clean install from USB I do not have the option to keep files and apps.
Is there a safe way to move the EFI system partition from the old HDD to disk C: (SSD with windows)?
Thank you.
