This question already has an answer here:
I recently installed Ubuntu again after having some troubles with my last installation. I've dual booted Ubuntu and Windows before but now i've got some problems.
After the installation Windows disappeared from the GRUB boot menu. I then tried to boot from the disk that my windows is located on, but i still get directly to GRUB, and i guess that's normal.
I've googled around a bit to try to fix this issue, but without success.
I've tried to mount my Windows disk and updating GRUB using update-grub, but it doesn't detect my windows installation.
Generating grub configuration file ... Found linux image: /boot/vmlinuz-4.15.0-22-generic Found initrd image: /boot/initrd.img-4.15.0-22-generic Found linux image: /boot/vmlinuz-4.15.0-20-generic Found initrd image: /boot/initrd.img-4.15.0-20-generic done
Using fdisk -l shows my windows disk as following
Disk /dev/sdc: 111,8 GiB, 120034123776 bytes, 234441648 sectors Units: sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disklabel type: dos Disk identifier: 0xe29d8236 Device Boot Start End Sectors Size Id Type /dev/sdc1 2048 232672357 232670310 111G 7 HPFS/NTFS/exFAT /dev/sdc2 232673280 234436607 1763328 861M 27 Hidden NTFS WinRE
What is my next step towards solving this, and could someone tell me what may be the cause of this issue, so that i can learn from my mistake?
EDIT: I found out that i accidentally installed in Legacy BIOS mode and not UEFI, and i guess that is why i'm having these issues. While trying to fix this my USB Memory device broke, so i guess i'll have to wait until tomorrow to dig deeper in this.
