revised Partition offset at 63 or 64?
more opinionated + include the explanation we found about offsets being 0-based, with 0 being invalid.

@user66229 ty. That explains the 0. (Ideally I could have guessed from online docs). The e command can also used to 'delete' partitions by resetting them to 0 - it looks like there's no separate delete command. Offset 0 is invalid because it overlaps the MBR, so I guess the non-zero size is just ignored (by the kernel?). In that case I think an offset value of 2048, or 64, would be aligned as I wrote in the answer.

expand MBR to explicate connection to partitions

I also just realized I don't know if grub.conf on your CentOS includes hard-coded partition numbers (which would need to be updated), or if it will just refer to the filesystem UUID. Sorry.

Ah, you probably don't need that. It's more relevant to the case where you install Windows, it overwrites GRUB, and you need to reinstall GRUB and add a GRUB entry for Windows.

Gah. If you found & followed that article from Googling - you could consider this a warning about the reliability of random relevant sources. I can't imagine what the point of that article is; it doesn't really provide anything over the built-in help from fdisk

comment Is LILO still usable on modern PC?
welp lilo is dead (and uboot deprecated) so yeah. What's the problem you had in mind? People aren't using FAT for /boot yet... BootLoaderSpec is a good project but not really there yet... and there's good reason for that (evil patents, FLOSS compatible license granted only for EFI interop).

@mikeserv I know, but loading a filesystem driver struck me as somewhat obscure for most cases. You'd even need to install some sort of EFI script (terminology?) to load the driver & then the kernel. Oh, & I bet no-one has MS secure boot signatures for these drivers so that's another wormcan :p.

-1 The (deb/ubuntu) kernel package will not update EFI. (EFI won't read fs that support symlinks, so you can't just use my answer). +1 for EXTLINUX as a newer alternative to LILO. Your link shows it supports several other filesystems which is a good sign. EFI support looks a bit new though, where that's necessary.
