Debian refusing to boot. Recovery mode doesn’t boot either. GRUB loader does show up.

Hello everyone. I have quite the problem. I am trying to set up Debian 9 to dual boot with windows on my desktop PC. I get here, https://photos.app.goo.gl/LfAqu9hziD3Bsxzi8, but then when I try to actually boot Debian this happens, https://photos.app.goo.gl/ZMd8JSTCtYAKHL438. I have tried booting Debian in recovery mode, but then this happens, https://photos.app.goo.gl/TMLGoJSGF7TRMeC36. The other problem is that GRUB won’t let me boot into Windows, so basically everything is not working. Any help on this matter would be much appreciated. Thank you!

Is the HDD formatted GPT? If it is, did you create an EFI partition?

I ask because I ran into a similar problem with Debian. The Debian imaged loaded on the machine by the vendor id not have an EFI partition. I had a Ubuntu MATE installation disk lying around because I'd just put it on my girlfriend's old Win7 laptop, and the installation routine suggested that I create an EFI partition. It did, and Ubuntu MATE has just been purring right along on that machine ever since.

Thank you for responding so quickly. I partitioned the disk through the Debian installer, and I am not sure, but I think it is EFI. Do you think reinstalling Debian/ re-partitioning the disk would fix the problems?

Just out of curiosity, did you change the system time on the BIOS?

at the grub menu press e for edit and add nomodeset to the end of the line that begins with linux

Which windows do you have? IF it is windows 10 it is almost certainly EFI. Did you turn off hibernation/fastboot on windows? Did you install Debian in Legacy mode? Open a terminal on Debian and run the following command as root which will tell you if you have an EFI partition.

parted -l
