This sounds like a failure in your boot loader. I notice that you say you use debootstrap to install the base system, rather than using the installer. Have you remembered to install a boot loader? debootstrap normally expects to be installing into a chroot or similar, so won't do all the necessary tasks that are needed for a bare-metal install. If you've installed grub (I suspect you want grub-efi-amd64, if you're using a 64-bit PC), check that the necessary files were loaded into /boot/efi (your partition #1 above). You may also get a "Debian" entry in your firmware boot selection menu. If, however, grub IS installed, how far through its boot does it get? Do you get a "rescue>" prompt? Do you get the menu up? etc. If you get a "rescue>" prompt, try the following (cadged from the Gentoo Wiki): insmod gzio insmod part_msdos # Probably don't need this, actually insmod part_gpt insmod diskfilter insmod mdraid1x insmod ext2 set root="mduuid/<tab>" linux /boot/vmlinuz blahblah inirtd /boot/initramfs blahblah Tab completion should be available, and SHOULD find the UUID of your raid (or produce an error, if not, hopefully) If you get as far as the menu, do you get any errors when you try to select Debian? > > Thanks. > > > -- > To UNSUBSCRIBE, email to debian-user-REQUEST@lists.debian.org > with a subject of "unsubscribe".
