Installing BC alongside a LiveCD ??

[peterr]

Have had major problems with Kubuntu, as the root is corrupted and it needs a reinstall. Want to backup some data to an external drive. I am able to boot to a live usb okay, but if I try and run Beyond compare there are all sorts of error messages.

So, with the computer booted to a Live usb, can I install Beyond Compare and use it. I wanted to use it to compare the backup before erasing.

It installed okay, so hopefully backup about 200Gb now.

So everything is running well now?

If not, what error text do you see when attempting to boot BC4?

[peterr]

Yes, all okay thanks Aaron. After the Live usb was used to boot ..

sudo mount /dev/sda1 /mnt
sudo bcompare

I had to use 'sudo' to run Beyond Compare, as there were some paths and files that were 'root' ownership.

Then when restoring today on another computer, needed a few of these to use the files/folders again ..

sudo chown -R username:group directory
