2 storage drives, 1 windows 8 drive, 1 ubuntu 12.10 drive. 1 ubuntu 12.10 live flash-drive

Previously my windows 8 drive would get wiped when installing to my 12.10 drive... so i unplugged the windows 8 ssd while installing. Now no matter what drive I boot to, I get nothing (except for the USB drive, it still works).

when I select a drive to boot to i get an UEFI windows boot manager option... and that successfully boots directly to windows.

Edit:
Tried EasyBCD 2.2 to no avail. A reinstall of ubuntu seemed to have done the trick.

It looks like a Windows install in sda in BIOS mode, Windows on sdc in UEFI mode and Ubuntu in sdd with no efi partition and grub in MBRs.

Drive sde seems to have some partition issue. But it is the MBR partition entry that is wrong, but no gpt partitions shown. The MBR exists only to make sure older tools like fdisk will not work on a gpt drive. Creating a partition may fix entry.

I would add an efi partition at the beginning of sdd and let Boot-Repair or manually convert the install to UEFI. Boot-Repair will uninstall grub-pc (BIOS) and install grub-efi (UEFI). To chain load then the Windows entry in grub on sdd has to have the UUID of the efi partition on the Windows drive.

Os-prober does not yet work with UEFI, so you can use Boot-Repair or manually add boot stanzas with efi and correct UUID.

It appears that the reinstall put the boot partition in place properly this time (I was able to choose "erase ubuntu 12.10 and reinstall" to ensure I was killing the right drive rather than trying to manually select it).

A minor suggestion would be for the ubuntu installer to let you pick a drive "manually" style and then automatically set it up.
The first install I had to select the drive manually and then set up the partitions myself.
Manually was the only way to select the drive I wanted but I didn't know how to properly set up all the partitions. Previous attempts to "erase full drive" just automatically erased my windows drive and I could not find a way to "use full drive" and yet still pick the drive. It might be there but I became hesitant to pick any option that even remotely mentioned windows.

I appreciate learning though in case this ever reoccurs in the future, but a full reinstall was no loss as I had not even been able to boot into ubuntu yet, so nothing there was lost.

Most of the auto install assumes one drive and sharing with Windows or totally overwriting the first drive.
Installs to a second or external drive require manual partitioning so you get the option on where to install grub2's boot loader. With efi it should always be to th efi partition but with mulitiple drive I have not idea how it would work.

Best just to manually partition or disconnect all other drives and install to the one drive you want to use.

Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!
hi everybody,
i hope i'm in the right place here. i've installed the 64bit version of ubuntu on my acer aspire netbook. and now i always have to choose efi boot by hand after the bios is done. i'm unable to boot automatically from the first boot device (namely my ssd)
the acer bios has no 'secure boot'/'legacy boot' option to choose from.

any ideas?

thanks in advance

@mtambo
You should be able to go into UEFI menu and choose ubuntu or grub as first boot device. Then it should default to ubuntu on reboot.
You may still have flash drive or DVD still set as first device? One time boot choice does not change default.

were should i find this uefi menu?
here is a screenshot of my bios boot order:

I have a ubuntu 10.04 LTS which is restored from a tar backup, but yet not bootable.

I remember the tar restore command said it had some errors, cant remember which though .

Now running boot-repair from 10.04 LTS live CD.

LVM2 is used but I dont have a RAID setup (though the pastebin text tells me so).

the problem I am trying to fix is that I get a kernel panic when the root volume is mounted during boot.

I cant chroot into the restored disk (getting a segfault), even though I have tried some different variants of mount --bind for proc, sys, and dev. Just experimenting here, following tutorials etc.

before the mount --bind I got the segfault on performing the chroot, now I get the segfault for every command I try inside the chroot.

Now, boot-repair tells me that I should enable grub2 repos for my target disk. I have enabled universe and universe update, which should be sufficient as far as I can tell. Still no cigar, and same error message.

I am suspicious that boot repair has the same chroot problem that I have, but actually reports it as a grub2-repo problem.

grateful for any help... Erik
