I think this should work but I would like to get a second opinion to save myself a headache. I have a Thinkpad T14s Gen1 (AMD). It is currently running windows 10 with BitLocker. I want to dual-boot it with Linux, since it only has one drive spot (I typically installed two drives and just pic at boot time when that is an option). I am considering the following course of action:
Back up with Macrium Reflect
Resize main NTFS Windows partition (with gparted)
Install Linux + Grub
Did I miss anything? is there anything I can do better? It has been a while since I dual booted on the same disk. Been using two disks for about a decade and this is the first machine I’ve had where this is not an option in a while.
Yes, gparted supports NTFS but I think it’s probably safer to shrink it in Windows Disk Management.
Just a heads up, BitLocker and grub don’t play nice together. There’s no issue with installing and using grub for linux selections but it will take you straight to the BitLocker recovery prompt if you attempt to boot Windows from it. But the the motherboard’s UEFI boot select menu works fine for starting Windows.
And everything else should be pretty straight forward. Don’t see you missing anything.
There’s a “unformatted primary” partition that is full? Then there is the EFI system partition, which shows up in both, then the C: drive. Then mystery 1001 MB partition with no information in Disk Management, but it is called “WinRE_DRV” in macrium.
Does anyone know what is going on with these partitions? Should I just resize the C: drive and ignore the other partitions?
I tested in a VM and couldn’t realign using Disk Management either. My advice is to shrink primary partition using DM and then use your tool of choice to move the recovery partition. Either gparted or Macrium (if free version allows) will likely work fine.
