Hello, YannUbuntu.
Yes. I still have this problem. Here is link for my boot-info: http://paste.ubuntu.com/1207043/ Let me ephesize my statement: If protective GPT record become first - then problem does not appears. It appears only if it is NOT first. Reason why I placed it NOT first - becouse my bios (which support UEFI) refuse to run MBR boot in case it detect protective GPT record. I have disabled UEFI in bios and using old fashion MBR boot. I have performed dist-upgrade so here are updated info: root@helena:~# apt-cache policy grub-pc grub-pc: Installed: 1.99-21ubuntu3.1 Candidate: 1.99-21ubuntu3.1 Version table: *** 1.99-21ubuntu3.1 0 500 http://ua.archive.ubuntu.com/ubuntu/ precise-updates/main amd64 Packages 100 /var/lib/dpkg/status 1.99-21ubuntu3 0 500 http://ua.archive.ubuntu.com/ubuntu/ precise/main amd64 Packages And here are info on version of GRUB root@helena:~# dlocate -l grub Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Installed/Config-files/Unpacked/Failed-config/Half-installed |/ Err?=(none)/Hold/Reinst-required/X=both-problems (Status,Err: uppercase=bad) ||/ Name Version Description +++-=============================-=============================-============================================================================ un grub <none> (no description available) ii grub-common 1.99-21ubuntu3 GRand Unified Bootloader (common files) un grub-coreboot <none> (no description available) un grub-doc <none> (no description available) un grub-efi <none> (no description available) rc grub-efi-amd64 1.99-12ubuntu5 GRand Unified Bootloader, version 2 (EFI-AMD64 version) ii grub-efi-amd64-bin 1.99-21ubuntu3 GRand Unified Bootloader, version 2 (EFI-AMD64 binaries) un grub-efi-ia32 <none> (no description available) un grub-emu <none> (no description available) ii grub-gfxpayload-lists 0.6 GRUB gfxpayload blacklist un grub-ieee1275 <none> (no description available) un grub-legacy <none> (no description available) un grub-legacy-doc <none> (no description available) un grub-linuxbios <none> (no description available) ii grub-pc 1.99-21ubuntu3 GRand Unified Bootloader, version 2 (PC/BIOS version) ii grub-pc-bin 1.99-21ubuntu3 GRand Unified Bootloader, version 2 (PC/BIOS binaries) un grub-yeeloong <none> (no description available) un grub2 <none> (no description available) ii grub2-common 1.99-21ubuntu3 GRand Unified Bootloader (common files for version 2) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/998097 Title: Grub2 not recognise GPT when presence hybrid MBR To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/998097/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
