My hard drive have Windows, Ubuntu and Debian installed. For some reason Debian is not showed in the grub list. If I use a bootable grub rescue software, it shows a message like this "Please create a boot partition greater than 200 Mb at the beginning of the disk". What is the size recommended for this partition? "greater than 200 Mb" is not particularly specific. The beginning of the disk contains the Windows partition. I am afraid that creating a Linux made Boot partition could break Windows. Have somebody been previously in this situation?

  • Is this a UEFI or legacy boot system? – kemotep Mar 24 '20 at 12:05
  • Was this message from Boot-Repair? It still suggest a boot partition inside the first 137GB of a drive. But that really only applies to old BIOS based systems. Have not seen issue with any newer UEFI based system. Post this: sudo parted -l – oldfred Mar 24 '20 at 14:25
  • @oldfred Yes It was Boot repair. I edited the question with the output of the command. I will give a try to create a boot partition inside the first 137Gb – birdman Mar 28 '20 at 19:45
  • @kemotep legay boot system – birdman Mar 28 '20 at 19:49
  • Unless really old system, may not need separate /boot partition. May be best to see details, use ppa version with your live installer (2nd option) or any working install, not older Boot-Repair ISO: Please copy & paste link to the Boot-info summary report ( do not post report), the auto fix sometimes can create more issues. help.ubuntu.com/community/Boot-Repair & sourceforge.net/p/boot-repair/home/Home Only use advanced options to update system. Auto fix will just default to first system seen. – oldfred Mar 29 '20 at 2:41
