DL380 G7 cannot find grub (alien.top)

I'm trying to set up my DL380 G7 as a home server, but I cannot seem to get it to boot.

I installed Gentoo, of which the minimal LiveUSB booted just fine, and I set everything up according to the gentoo handbook. After I was done with the installation and rebooted, it couldn't seem to find my installation at all. Symptom: I tell it to boot from HDD, black screen for a while, and then it just reboots.

AFAIK, I set up everything correctly. My HDD uses MBR, with the first partition being the xfs boot partition. I also installed grub for a non-EFI system (the DL380 G7 doesn't support efi, right) without any errors.

Pls help, I'm at my wit's end

Is there a RAID controller in your machine?

[–] XerneraC@alien.top 1 points 1 year ago

Actually yes, haven't thought of that

If you haven't figured it out already, make sure the the RAID volume you installed to is the controller's selected boot volume. If you have multiple controllers, ensure the controller the drive is on is set as the first boot option.

I have 1 controller. I‘ve set it as the boot controller. I‘ve put HDD boot option as my top option in the boot order. Still nothing. Is there maybe something on the grub side that I could‘ve messed up?

It's possible that grub is being installed incorrectly. I don't have much experience with Gentoo, but I do with Linux and system recovery. If the machine is unable to find the bootloader then it's likely not installed correctly.

You can try installing another distribution such as Mint or Ubuntu and see if it boots normally. If it does, then it's indeed a grub installation/configuration problem. If not, then it's a BIOS configuration issue.

Take note that the Gen7 also does not support UEFI, that wasn't until the Gen9. So your partitioning format or set up may also(but rarely) cause problems.
