I have dual booted windows 10 along with fedora 37, but grub menu does not give an option to select any operating system, it just directly boots into fedora 37. I first thought that i had deleted my windows 10 but i can still see my windows 10 files in other locations in nautilus. please help i am dying
What do you get if you run
sudo os-prober in a terminal? By running this command it will detect every possible os installed on your computer. If it detects your windows 10 installation run
sudo grub2-mkconfig -o /boot/grub2/grub.cfg this will update the grub menu using the grub configuration file.
it shows nothing
What do you get if you boot to fedora then run
What is the result of
Please post the output of both those commands as preformatted text using the
</> button above.
Did you install fedora in legacy mode while windows was in uefi mode? or vice-versa?
If both OSes are not installed in the same boot mode then you will be unable to boot both from grub. Only fedora will be available from grub in that situation.
I get this when i type the first command you mentioned

i dont really get what any of these mean , i have never used linux becuz. I appreciate your help plz also keep explaining
Right there is the issue.
Windows is installed in uefi mode and you installed fedora in legacy mode as can be seen with /dev/sda6 as BIOS boot.
The simplest recovery is to delete the partitions sda6, sda7, and sda8 then reinstall fedora in uefi mode. It looks like all of windows should be fine as is.
You can boot to the live install media in uefi mode by opening the bios boot menu (normally by using one of the function keys between F8 and F12) and selecting the install media device marked as uefi. Once the live media is booted you can delete those 3 partitions with fdisk or gdisk.
Once you have deleted those 3 partitions then boot again into uefi mode and the install will automatically be done in that mode.
It may be worthwhile to actually enter the bios and set the boot mode to ‘UEFI only’ since windows is already installed that way.
correct me if i misunderstood i would have to boot windows from bios? and then delete the linux partition and then reinstall linux right. i would love to go back if i can
You would boot the install media used to install fedora. Windows cannot see nor manage the linux partitions.
- boot into the bios and set the boot mode to
uefi onlyand save it. (all future boots will always be uefi mode now)
- boot the install media which will give you the live media, (now booted to uefi mode since the bios can now only boot into that mode.)
- Use a command line in the terminal app to run gdisk or fdisk and delete the 3 named partitions. /dev/sda6, sda7, & sda8
- reboot again with the install media. (needed because of changing the partitions on the drive)
- install fedora (which will now be installed in uefi mode, since that is the way it was booted)
After this when you next boot you should be able to boot fedora (default) or select windows to boot.
Thank you so much. I love you
