Public bug reported:
I have Ubuntu 18.04.2 LTS and grub 2 installed which boots from a sata
SSD drive. This a BIOS system, not UEFI.
I have a Windows 10 system restored to an nvme drive on a pci-card. I
can boot this windows-10 system in VirtualBox.
Ubuntu can see my nvme drive perfectly well, and update-grub finds the
Windows 10 system. Here is the generated section of /boot/grub/grub.cfg
:
### BEGIN /etc/grub.d/30_os-prober ###
menuentry 'Windows 10 (on /dev/nvme0n1p1)' --class windows --class os $menuentry_id_option 'osprober-chain-4E76C42676C4111F' {
insmod part_msdos
insmod ntfs
if [ x$feature_platform_search_hint = xy ]; then
search --no-floppy --fs-uuid --set=root 4E76C42676C4111F
else
search --no-floppy --fs-uuid --set=root 4E76C42676C4111F
fi
parttool ${root} hidden-
drivemap -s (hd0) ${root}
chainloader +1
}
blkid can report on the drive:
% sudo blkid /dev/nvme0n1p1
/dev/nvme0n1p1: LABEL="OS" UUID="4E76C42676C4111F" TYPE="ntfs" PARTUUID="000131d8-01"
However, when booting the Windows 10 Entry from grub, I get 4 errors:
error: no such devices 4E76C42676C4111F
error: not a partition
error: device format "lvmid/ozz..." invalid must be (f|h)dN, with 0 <= N < 120.
error: invalid signature
My belief is that if update-grub can create a grub menu entry. The
devices referenced in that entry should be able to be found by the grub
boot-loader runtime.
I have _minimal_ expertise in grub2. I suggest either the grub menu
entry has been incorrectly generated or interpreted, or perhaps the
driver required to see the nvme drive is not available to the grub
runtime.
