bitlocker - dual boot

Hi, my work PC windows partition has recently been protected by bitlocker.
This removed grub and installed a Microsoft bootloader, so I cannot boot into my linux partition anymore, I removed the linux partition.

Is there a way to install Linux again on the remaining partition without changing the bitlocker boot hash ?
For example installing linux on the free HD partition and boot from an usb stick with only a small boot partition that points to the rest of linux on the HD,
partition in order not to change the bitlocker bootsector ?

If you want to install Mint to the hard drive, you can install Grub to the USB drive during installation.
Before running the installation program, open a terminal and enter the command:

Code: Select all

lsblk
That will tell you if your USB is /dev/sdc or /dev/sdd or ?
Then use the "Something Else" option during installation and chose /dev/sd? for the bootloader location.
It is at the bottom of the partitioning screen.

Thx, I'll give it a try as soon as I get the bitlocker access code you need to unlock the PC when you forget the digit code needed when starting the PC.
Up to now I did not dare to boot from USB as I was affraid it would corrupt the bitlocker checksum.
