so yesterday I changed from Linux Mint to Manjaro with Gnome and wanted to just remake my grub config. Sadly grub does not find my Windows Boot.

Output from lsblk:

sdb                                                                         
├─sdb1
│    ntfs         SystemReserved
│                       01D50D5FDB172900                                    
├─sdb2
│    ntfs         SYSTEM
│                       01D50D78773A8C60                                    
└─sdb3
     ntfs               01D50D7891E5C9D0

Edit: os-prober is also installed, but yields no results!

Can you guys help me (Grub worked before with Mint and Windows DualBoot)

  • So far there was nothing that would have helped me sadly. – Avocari Feb 11 '20 at 22:25
  • Have you tried booting a Windows disk to get to a Command Prompt? Is it UEFI or other? Windows Command Prompt bcdboot C:\Windows where C:\Windows is your partition for Windows. – vssher Feb 12 '20 at 13:30
  • How do I distinguish between UEFI and other here? – Avocari Feb 16 '20 at 08:36
  • Which ever is the largest hard disk partition I would imagine. You might want to use Microsoft's Diskpart. At at Windows Command prompt type "Diskpart" it will open with a prompt. Type select disk 0 then type List partition that might tell you which partitions Windows is on. If It does not, type List volume it should be the 2nd partition on the hard drive, List Volume should give you a drive letter also, if they exist. – vssher Feb 16 '20 at 23:24

You need to mount your Windows Partition first!

If this is not working try to install ntfs-3g with sudo pacman -S ntfs-3g and remount your Windows partition.

Then try sudo update-grub
