Linux is on USB drive, and hard drive is on windows, a pc on which I do
not have right to write MBR (company policy) or install anything;
I have grub2 writing on a hard drive MBR automatically sometimes during
upgrades of the Kernel;
I would like to exclude any kind of writing permits to grub2 on the hard
drive MBR; is it possible?
xubuntu 18.04
best regards
Paolo

Title:
[karmic] grub re-writes boot sector on wrong drive on fresh install
Status in Mythbuntu:
Invalid
Status in grub2 package in Ubuntu:
Invalid
Bug description:
I attempted to install mythbuntu karmic/9.10 alpha 4 to a USB drive.
Using a laptop with an IDE drive containing Windows XP, I booted from
the ISO image CD-ROM and went through the installation, selecting
manual partitioning, and creating a single EXT4 root filesystem on a
USB drive. The installation proceeded through the complete install
to the USB key until instructed to reboot.
I re-booted the laptop with the USB key inserted, and was presented
with the message "No bootable partition in table". Then, removing the
USB key and booting from the laptop IDE drive (which should not have
been touched by the mythbuntu install) I get the message "GRUB
loading. Welcome to GRUB! Entering rescue mode... error: no such
disk" followed by the "grub rescue>" prompt.
I examined the laptop hard drive with a partition editor, and the
Windows partition is still intact.... but it looks like the boot
sector has been re-written mistakenly.
Now I have two problems.....
1) how do I get Windows on my laptop to boot again.... I need my work data!
2) how do I make my mythbuntu USB front-end install bootable?
