A work issued laptop has and an IT mandated drive encryption installed to protect data on the primary OS that I'd like to install Linux Mint on. I've asked several times to have drive encryption removed, but IT doesn't want to budge. Moreover, while they don't seem to have any issue with installing my own flavor of Linux, they are extremely slow to fix things, so I'd like to avoid breaking anything.

When I boot from Live CD, Linux Mint doesn't understand that the existing drive is already partitioned and contains data on it. Thus, resizing it from within LinuxMint seems like a no-go.

It is unclear what actually happens when I resize and repartition the encrypted space from withing the existing OS. From experiment, the new partition is visible from the Live instance of Linux Mint, however, the data it contains is also encrypted. Yet, I've been unable to determine of the encryption software does anything to redistribute the block / sector locations, and if any of the first partition's data might actually be housed within what appears to Linux Mint as the 2nd partition.

My attempts at getting an MD5 has of each partition before and after altering the data in the primary OS seems to indicate the drives are indeed separate. But, I'm not entirely convinced that this small test is enough. Is there some other test I should run?

As an alternative to creating a new partition, I tried installing a version of Grub from within the original os and pointing it to an image of a live CD. However, attempting to boot to this live CD produces a "device not found" error.

Is there a way to create a virtual drive, or partition off some space that I can be sure won't be touched that I can install Linux Mint into? And if so, how do I point Grub to the new install?

  • I found this how-to, but EasyBCD seems to be paid software now: wiki.archlinux.org/index.php/Dual_boot_with_Windows/SafeBoot Thus, I'm still having trouble getting a boot loader to point to my linux partition. – virtualxtc Jun 25 '18 at 20:23

    I'm voting to close this question as off-topic because this is related to finding tools to open McAfee Driver and install Linux as a file inside of it, or resizing this encrypted proprietary software. – user34720 Jun 25 '18 at 20:27

    Agree, we cannot allow another one to move from Windows to Linux. – ajeh Jun 25 '18 at 21:31

    @virtualxtc Sorry, but creating a virtual drive file inside windows AND inside an McAfee encrypted disc, to me, still seems to be offtopic. You should find better help at superuser.com. Same way as asking on how to resize this drive to shrink it and make Windows or McAfee bootloader in this case point to your partition installed grub. It's not (just) about being proprietary(and adjective that i used), it's about being offtopic cause we can still help you if the question is about luks, ecryptfs or any other encryption technology that IS related to Unix & Linux. – user34720 Jun 26 '18 at 10:38
