How do I setup up dualbooting?

There’s usually at least two non-volatile. One holds the BIOS itself with optional dual-bios chips as backup, and one for user settings and the like I was referring to above.

99 free or 99 total? I think thats just the standard size that windows 10 creates. You can free up space by removing old unused bootloaders (don’t need a seperate grub install for every linux OS, just rebuild the config from whatever OS you originally installed grub on and it should be able to find their entries. the kernel images are big though)

I guess this doesn’t apply to legacy BIOSs?

Its consuming 33 MB of data and the partition has 99 MB of total storage, sorry I should have been more clear.

Ah I see, thanks :slight_smile:

Use this command to show your UEFI firmware’s NVRAM boot entries:

efibootmgr -v

It should also show the boot order.
