I need to install a legacy linux system on a new NUC computer.
In the bios, the legacy options are greyed out even after disabling UEFI boot.
I've tried to upgrade / reset the bios settings and change the hard drive (NVMe -> mSATA) but the options are still greyed out.
Anyone have a solution for this ?
Thank for your quick answer.
The NUC and the hard drive are brand new and never had a OS installed on them.
We did , in fact use a NVMe SSD drive , if we replace it by a M2 SATA, can this enable th elegacy options, if not have we a solution to "reset" the BIOS to a state with the options availble?
Hi @Shalien ,
Have performed this test again on NUC7i7DNHE. This time I've removed the Optane memory module, changed SATA mode to AHCI, disabled UEFI boot and finally enabled Legacy boot. After pressingg on F10 (Y), the NUC successfully booted to USB with Legacy MBR boot. So, try to do this on your NUC. You don't need SSD for this test, just bootable USB. However if the Legacy boot option in your NUC can't be enabled after disabling UEFI boot, you can't do this. In my other NUC - NUC8i7HVK, legacy boot option doesn't exist in Bios at all.
The NUC8i7HNK, NUC8i7HVK and NUC8i#BE* NUCs do not have a CSM in their BIOS and thus cannot support Legacy boot. In this day and age, there is simply no acceptable reason for why you would require Legacy boot. All Linux distros that have support for the processors and chipset used in this generation also have support for UEFI boot.
