Package: Debian stable installer
Version: 10.7.0, and 10.8.0
Severity: Critical
Hard drive was formated as GPT. Installer will not write to disk after
setting up file system/partitions if an EFI partition is created first.
Error message indicates "Can't write to disk". Once the EFI partition is
removed then the installer will write to disk. This presents a problem
to people wishing to dual boot with EFI partitions on a GPT formatted drive.
Hardware that this occurred on is a Dell XPS 15 7590. This laptop came
out in late 2019.
One of the key benefits of a GPT formatted partition is being able to
install windows in any order -- first or last. But that won't be
possible on this laptop because Linux has problems with EFI if installed
first. No test was done to see if a problem would occur if the EFI was
installed last.
