Will disk protected with passphrase and encryption cause an issue if I attempt to update BIOS?

I have a Dell T5810 with Intel Xeon E5-1650 v3 processor (6 core, 12 thread) and Nvidia 1060 6 GB GPU. I am interested in upgrading the CPU to the Xeon E5-2687W v4 (12 core, 24 thred) to look at improving performance in games. The processor is only about $40. I suspect that upgrading the gpu will also be needed, but I would like to see how the performance does after each step. Anyway, in reading about this, it was recommended to updated the bios before the cpu is changed. I found instructions for this on linux Dell systems: Update the Dell BIOS in a Linux or Ubuntu environment | Dell US . In other reading, I noted that there were comments about the need to turn off Bitlocker (I gather this is disk encryption in Windows systems) before updating or there might be problems in booting after BIOS updating (disk not identified, etc). Since I have two drives (one bootable for the Garuda OS, the other only data–no dual booting) that are both passphrase protected and encrypted, I wondered if there would be issues with doing a BIOS update in Garuda OS/linux. Does anyone have experience with BIOS updating with protected encrypted drives in Garuda OS? Thanks in advance.

Any significant change to the system’s hardware or firmware (including a BIOS update) can trigger BitLocker to enter recovery mode. From there you would need to manually enter the Bitlocker key to gain access to the disk.

I guess that is more or less the point of TPM, so: fair enough.

LUKS encryption on Linux can be made to work with TPM in a similar way, but it is not the default. You would have to explicitly set it up to work like that. For the sake of your BIOS update, it’s something you don’t need to worry about.

Depending on the motherboard and the update process, there is always a chance you’ll run into little “gotchas”. For example, a couple years ago a Framework BIOS update wiped the EFI boot variables ([RESPONDED] Arch BIOS Update Guide - Linux - Framework Community). It was a very simple fix, but probably caused some panic for folks who were not expecting that.

In general though, these days a BIOS update is typically a fairly trivial process. Just follow the vendor’s instructions and be careful, and you should be fine.

Thanks!

Update: I updated the BIOS on the Dell t5810. All of the bios A12 and later for this machine will support the E5-2687w v4. No issues at all with encrypted disks, the grub loaded the OS normally after the bios update. Machine has 4x faster multithread geekbench6 after the CPU change. Now, a new GPU to follow!

Good for you, glad to hear that fixed things for you. So many people are resistant to updating their bios in Linux because it can be more complicated than the way it worked in Windows. So much troubleshooting effort is wasted on the forum trying to correct an issue that can can only be fixed by updating the bios.

Good on you for doing things properly and getting that bios updated.
