Boot failure after GRUB 2.0 installation

Another option is to try kexec if it comes installed with GParted.
Something like this:

mount -t ext4 /dev/sda7 /mnt
kexec -l /mnt/vmlinuz --append=root=/dev/sda7 --initrd=/mnt/initrd.img
kexec -e

Well I know it is dev/sda2 but what I get from "ls" is not likely close to it?

(hd0, msdos2)

I am not sure how chroot works from Gparted Live, since you have no other linux to boot. Try this in terminal:
(I assume you will be root, or first google how to execute root commands in Gparted Live terminal)

mount /dev/sda7 /mnt
mount --bind /proc /mnt/proc
mount --bind /dev /mnt/dev
mount --bind /sys /mnt/sys
chroot /mnt
grub-install /dev/sda
exit
umount /mnt/sys
umount /mnt/dev
umount /mnt/proc
umount /mnt

That is a chroot procedure. Hope fully it will work.

And get a new usb stick, it least 1GB and make it ubuntu live usb, and keep it.

When I get to "chroot /mnt" it says

chroot: failed to run command '/bin/bash': Exec command error.

Ok just borrowed the neighbors usb (should have thought of that earlier ), installed ubuntu live, then boot-repair and now it's working. Boot-repair summary: http://paste.ubuntu.com/1613807/

This better teach me a lesson that I should keep an Ubuntu disc with me at all times.

It looks like you can't do it from Gparted Live, as I assumed. It is not a "full" linux distro.

I can't understand what is the problem using the same stick for Damn Small Linux or Puppy Linux. You said it would overwrite Gparted Live. So what, it's not even a full distro, as you can see yourself. It serves only for partitioning, and you have partitioning tools in one form or another (GUI or command line) in the mentioned distros too.

So, you don't lose anything by overwriting Gparted Live, but you can gain much. It's up to you.

Investigate first and confirm that the distro you want to use can fit on the stick.

Then that would be #1 on my to-do-list, while my computer's now working. Thanks a lot!
