[SOLVED] Best way to kill partitions and get grub2 back?

[chipps61]

So I'd been toying with the latest Sabayon on a triple boot with Vista and Mint 8 main. Hadn't booted into Sabayon in a few days so did so last night, and there were over 500 updates. I did them all, and on a reboot afterwards Sabayon went ballistic and that installation is now hosed. I'd love to just kill the / and /home partitions I'd created for it and go back to a dual boot between Mint and Vista. The question is... what's the best way to go about doing that?

I know I can just kill the two Sabayon partiions and then boot from CD and reinstall Mint 8 (which will reinstall Grub2 and find Vista in the process), but ideally it'd be nice to manually kill the partitions, find some way to update Grub2 after that before rebooting and get back to where I was before I started playing with the triple boot.

Is that the best way to approach it? Right now Sabayon's grub has control, as that's the last OS I installed.

Here is my current partition setup from fdisk -l:

Code: Select all

   Device Boot      Start         End      Blocks   Id  System
/dev/sda1               1         192     1536000   27  Unknown
Partition 1 does not end on cylinder boundary.
/dev/sda2   *         192       41965   335544320    7  HPFS/NTFS
/dev/sda3           41966       52591    85353345    5  Extended
/dev/sda4           52592       60801    65946825   83  Linux
/dev/sda5           41966       42208     1951866   82  Linux swap / Solaris
/dev/sda6           42209       43667    11719386   83  Linux
/dev/sda7           43668       52591    71681998+  83  Linux

sda6 and 7 are the ones I want to remove and also remove from grub2. sda3 is Mint 8's /, and sda4 is Mint 8's /home. Any suggestions appreciated - this isn't an immediate need, but at some point I'll have to deal with it, as my default boot (Sabayon) is now broken.

You can use gparted on the mint livecd to remove the partitions and resize the remaining ones if you wish. You can also install grub from there without re-installing mint, see http://members.iinet.net/~herman546/p20 ... stall_GRUB and https://help.ubuntu.com/community/Grub2 ... m%20LiveCD

To save yourself from having to use the Live CD:

1) Boot into Mint, start Gparted and delete the offending partitions

2) Then from a terminal

Code: Select all

sudo grub-install /dev/sda

3) Then

Code: Select all

sudo update-grub

Beautiful - that's exactly what I was looking for, and worked perfectly. Thank you!
