Debian 9 grub boots to command line but works SOLVED

[justinmk85]

I figured it out finally I wasn't able to use the debian installer to clear the disk because it has to have a root file system specified it wouldn't just clear it.
After doing some more research I found a way in terminal to clear the entire disk and the mbr (installer wouldn't do that). I finally got root access using debian live session root terminal and used this:

Code: Select all

dd if=/dev/zero of=/dev/mmcblk0 bs=512 count=1

Ran debian installer after that and installed. After reboot the issue was fixed.

Thanks for all the help everyone!

Very cool.

So the first sector had some code there that Debian installer was not able to delete.
So that is why there were 2 partitions for efi.

Great Job.

Just for the record:

Code: Select all

dd if=/dev/zero of=/dev/mmcblk0 bs=512 count=1

That command will not clear a GUID partition table ("GPT disk") because of the backup tables elsewhere on the disk.

To clear disks with a GUID partition table, install the gdisk package and run:

Code: Select all

# sgdisk --zap-all /dev/sdX
