OS Installation
My machine is configured (during installation) to have Secure Boot disabled. After completing the installation, I will re-enable Secure Boot in the Secure Boot section of this guide.
Important
If you already have an EFI partition on your machine and don’t want to use it for the EFI of your
Debian installation, you’ll either need to detach the disk that contains the EFI partition or fix the EFI partition
mapping in
/etc/fstab after installation completes. For the latter, you can follow
these instructions.I have manually set my disks up during installation as:
| Partition Type | Size | Mount Point | File System |
|---|---|---|---|
| EFI System | 512M* | /boot/efi | EFI System/FAT 32 |
| Boot | 512M* | /boot | FAT32 |
| LUKS-encrypted LVM | 100% | / | ext4 |
*: These are recommended sizes. I’ve gotten away with the EFI and boot partitions set to 300 MB, but you’ll have to do a bit of clean up earlier on in the process.
