Bug Description

I used USB-Creator, to install an ISO onto my USB-pen-drive:
SHA256 44cc15a31f9a3a6b583929ce711a5eb76fddb1ba447726f9bb2539d78b7a53bc

After booting from the drive, I ran the internal sanity check on boot from the GRUB-menu, resulting in two files failing.

So I found file md5sum.txt in the root-directory of the device and checked:

f05f09712e02752e371b1e5542f48fec grub.cfg
3f3de40dda154fb20c3f43d20e27d1f0 grub.cfg~
4a38e0138d9e1bf6eda073cb08e7d549 loopback.cfg
fbf91ea5dab2df948318aeb3f4278436 loopback.cfg~

Where the files with ~ are wrong, before replacing them with their correct copies manually extracted from the ISO.

This is unfortunate but currently an expected side-effect of installing with usb-creator, especially if you enable the persistence option: we need to update grub.cfg and loopback.cfg accordingly so that it will be enabled and usable.

Perhaps there may be a way to also mangle the sums file to follow the changes, or removing them from the sums completely.
