[Bug 1561842] Re: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.
Just checking my email this AM and reading your recent replies to Ubuntu GNOME mailing list i see you included a boot info summary with both the Windows drive and the Ubuntu drive connected: http://paste.ubuntu.com/15574213/ The output of parted -l shows Win 7 is installed non-EFI but Ubuntu is installed in UEFI mode: === parted -l: Model: ATA Hitachi HDS72101 (scsi) Disk /dev/sda: 1000GB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End SizeType File system Flags 1 1049kB 18.3GB 18.3GB primary ntfs diag 2 18.3GB 18.4GB 105MB primary ntfs boot 3 18.4GB 1000GB 982GB primary ntfs Model: ATA ST3750528AS (scsi) Disk /dev/sdb: 750GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start EndSizeFile system Name Flags 1 1049kB 538MB 537MB fat32 EFI System Partition boot, esp 2 538MB 742GB 741GB ext4 3 742GB 750GB 8569MB linux-swap(v1) Model: USB Flash Disk (scsi) Disk /dev/sdc: 2005MB Sector size (logical/physical): 512B/512B Partition Table: msdos Disk Flags: Number Start End SizeType File system Flags 1 16.4kB 2005MB 2005MB primary fat16boot Model: Generic- SD/MMC/MS/MSPRO (scsi) Disk /dev/sdh: 15.8GB Sector size (logical/physical): 512B/512B Partition Table: loop Disk Flags: Number Start End SizeFile system Flags 1 0.00B 15.8GB 15.8GB fat32 That is, in itself, problematic. So please open a new thread at Ubuntu Forums here: http://ubuntuforums.org/forumdisplay.php?f=333 One of the forum mods there uses the moniker oldfred and he'll be able to answer your question and help you get that straightened out. My method would be to back up all the data on the Ubuntu drive and reinstall in non-EFI mode after creating a new msdos partition table on the Ubuntu drive, but there may be a simpler way :^) Please do be patient and wait for oldfred to reply. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1561842 Title: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.

[Bug 1561842] Re: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.
@Phillip Susi No, I'm not able to find a particular cause for it. As I had said, the system works and acts perfectly normal before this happens and works normal after installing grub again. I'm a bit confused as to how the motherboard/BIOS could have just *forgot* that Grub existed. Not that I'm calling you a liar or anything, its just I've had Windows 10 Insider Preview(UEFI install) and SteamOS(for a short period of time, anyway) as well as Windows 7 that came with my computer installed had/has no such issues. @Erick I'm very certain the Windows 7 HDD isn't UEFI as I've never seen any indication that it was. If it matters any, I have two Ubuntu boot options for Ubuntu Gnome: 1: ubuntu 2: UEFI: ST3750528AS (hard drive model) Booting into the UEFI option causes the screen to flash blue and text to appear for not even a second before showing the GRUB bootloader. I don't know what it says as it flashes so fast. Booting into the "ubuntu" option just takes me straight to GRUB menu. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1561842 Title: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.

[Bug 1561842] Re: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.
Based on what's said in comment #3 I suspect that there is an EFI System Partition on both the Windows drive (which was disconnected when boot info was gathered) and the Ubuntu drive. That becomes problematic and really is just a limitation of UEFI in itself. I still frequently run into problems with UEFI that require I ask a question at Ubuntu Forums and wait for oldfred to get me straightened out. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1561842 Title: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.

[Bug 1561842] Re: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.
I'm afraid this looks like a bad motherboard/firmware; it appears to have simply "forgot" that it should boot grub.

[Bug 1561842] Re: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.
I've personally never used update-grub before, so unless the command was given by an update, no. I run Windows 7 and Ubuntu Gnome on separate hard drives. I had unplugged the Windows 7 HDD for the boot-repair. Don't think so since it happens when restarting from Ubuntu Gnome and never from Windows 7 to Ubuntu Gnome if the option was there before restarting Ubuntu Gnome. If it matters any, I get a duplicate UEFI entry for Ubuntu, named after the hard drive model(Model: ST3750528AS). If i select it, the screen flashes blue and enters grub as normal(or looks normal, anyway). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1561842 Title: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.

[Bug 1561842] Re: Grub bootloader disappears after a seemingly random amount of restarts/shutdowns.
Grub shouldnt just disappear! Does running "update-grub" break it? (that would get triggered from time to time on system updates) You dual boot with Windows? Is it possible that Windows is messing with the UEFI Boot Manager? Or does it happen when you reboot from Ubuntu?
