Suggested repair: ______________________________________________________________

The default repair of the Boot-Repair utility would reinstall the grub2 of
sda5 into the MBR of sda.
Grub-efi would not be selected by default because legacy Windows detected.
Additional repair would be performed: unhide-bootmenu-10s win-legacy-basic-fix

Confirmation request before suggested repair: __________________________________

LegacyWindows detected. The boot of your PC is in EFI mode. You may want to retry after changing it to BIOS-compatibility/CSM/Legacy mode.
Are you sure you want to continue anyway?

Final advice in case of suggested repair: ______________________________________

Please do not forget to make your BIOS boot on sda (ATA ST2000VX000-1ES1) disk!
Please set your BIOS in Legacy mode in order to start your Ubuntu 20.04.3 LTS, then type command [sudo update-grub] in order to add the Windows entry to your GRUB menu.

EDIT.

The error tha appears while Installing ubuntu is: Executing grub-install dev/sda6 failed. This is a fatal error.

The message that appears when I try to fix the above error with boot repair is: LegacyWindows detected. THe boot of your PC is in EFI mode. You may want to retry after changing it to BIOS-compatibility/CSM/Legacy mode. Are you sure you want to continue anyway? When I proceed, the reports that I have attached occured.

Also, sda5 is my main linux filesystem, sda6 is the EFI system and sda7 is the swap space. When I had to pick the place for Device for boot loader installation I firstly picked the sda5, and afterwards and sda6. Should I pick sda?

It would help if you told us what the error was when you installed Ubuntu. But we are where we are. Have you tried booting in to the firmware (normally F10 on boot) and selecting the boot options. It will normally give you an option to booth from a specific disk. If you boot in to /dev/sdc it should offer you a GRUB menu so that you can choose which OS to boot: Ubuntu or Windows. try that

I tried that, but no boot is performed in any disk. The error was something about the grub installation. I also used boot-repair and a new report has been created reporting this error. Here is the link for the new report. Also I should mention that in the process of partitioning the disk, I created and ext4, an EFI and a swap portion from an allocated disk. https://drive.google.com/file/d/1sg2H6pz9Kc_63Zs0UYSYk26yvXHy9UvJ/view?usp=sharing

Well, marking my answer down is not going to improve it! Looking at your disks, which on has the EFI boot partition on it? If its on SDC1 then the format should be FAT not vfat, and definitely not ext4. The part of the install program that write the EFI gets a bit picky about this. I am also a bit concerned about sda6 - is there an error in the partition table for this disk?

I recommend trying to boot using Super GRUB2 Disk. You can download it from https://sourceforge.net/projects/supergrub2/ Make sure you can unpack the ISO image on an external drive, like you would with the Ubuntu ISO

I believe I have understand the problem. I tried to install Linux UEFI while windows are on Legacy mode, that's why grub could not be installed. Yet, now I cannot enter windows either. I managed to enter grub through a Super Grub2 with a USB stick. And now what?!

Now you should make Windows installation media and boot from it to repair Windows. Or, better, reinstall it UEFI mode as any Windows or Linux should be in any UEFI hardware, i.e., any consumer line computer since 10 years ago. Then install Ubuntu properly in UEFI mode.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
