How do I get rid of Pep 8 from my dual boot (Solved)

Hi Mark,
Is there an easy way to get rid of Peppermint 8 from my dualboot Pep 7 and Pep 8 system ??

Don W

Boot into Peppermint 7, and post the output from:

sudo fdisk -l


sudo blkid



if it’s Peppermint 8 you want to get rid of, make sure you post the output from those commands whilst booted into Peppermint 7

Hi Mark,
Hows this ?

Okay, basically you need to boot to a LiveUSB … then use Gparted to

a) delete /dev/sda4 (which is the Peppermint 8 partition)

b) move /dev/sda3 to the end of the drive (sda3 is the swap partition, moving it to the end of the drive will leave room to expand sda2 into, sda2 being the Peppermint 7 partition)

c) expand (NOT move) /dev/sda2 into the free space (so the now free space is available to Peppermint 7)

If I were you, I’d create a LiveUSB, boot to it. fire up GParted and take a look at the partition layout, and make sure you understand what I just suggested BEFORE actually doing it.

Hi Mark,
I carried out those suggestions and it looked as if everything was well.
I logged out and logged back in and got this message

GNU GRUB version 2.02~beta2-36ubuntu3.17
Minimal BASH-like line editing is supported.
For the first word, TAB lists possible command completions.
Anywhere else TAB lists possible device or file completions
Any ideas ?

Are you able to select “ubuntu” from the EFI boot selection screen ?

if you don’t know how to get to the EFI boot selection screen, what make/model is your laptop ?

Boot to a Peppermint 7/8 64bit LiveUSB and run these commands in sequence:

sudo mount /dev/sda2 /mnt


sudo mount /dev/sda1 /mnt/boot/efi


for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done


sudo chroot /mnt


grub-install /dev/sda



then hit Ctrl+D to exit the chroot environment

and reboot to test.

Thanks Mark,
That did the trick :smiley: :smiley:
It was a bit cheek clenching entering those commands manually but all is well again.
Thanks again, great karma.

Glad I could help … can you please remember to mark the topic (SOLVED) Don :wink:
