Some months ago I put together a new build, installed Win10 to the m.2 drive and Manjaro to a SATA SSD. Everything worked fine for months - system boots to the grub menu, I choose which O/S to boot to…everything works. However, I always wondered about the drive that was created in Win10 that contains one folder named “EFI” and under that, two subfolders: “boot” and “Manjaro”. I was concerned that this drive was ‘exposed’ via Win10 and might get into trouble. I renamed it “Manjaroboot” and set it as drive L:. Again, all was working fine until recently. I noticed that the Userbenchmarks tool tried to write to that drive (and in fact created a folder there). Now, when I try to boot to Manjaro from grub, I get all sorts of problems, from black screens, to frozen startup splash screens, to a desktop with no mouse, etc., depending on which of the fallback options I choose from grub. In any case, none of them work properly, and though I can boot to Win10, I can no longer boot to Manjaro except in this terribly crippled way.
So, I’m wondering if a) this Manjaroboot drive has been corrupted in some way? b) can that drive be hidden or locked so Win10 never tries to write to it (or allow it to be written to)? and c) is there a way to fix my corrupted Manjaro install without completely re-installing the Linux O/S?
Thanks for any insight.
