Xubuntu 12.04 Amd64 installed on an HP dv6t-7200 laptop (EFI and
Win8), gave the following results. If I just powered up the machine, it booted Win8. If I pressed F9 during POST to get to the boot selection in the BIOS, I could choose "ubuntu", which then gave me Grub. Selecting Linux from Grub worked fine, but the Grub entries for Windows and Windows Recovery didn't work.
Perhaps I should have left well enough alone, but I then booted a CD of Ubuntu 12.04.1 Secure Remix AMD64 and ran BootRepair. I let it update itself from the web site, then chose the default repair.
After that, Windows no longer boots at all, either from the OS Boot Manager or from Grub. From the OS Boot Manager, HP's substitute for a wristwatch icon, a string of balls chasing each other around a circle, continues indefinitely. The same happens if I attempt HP's "automatic repair" function from F11 during startup.
Linux still runs fine (booting via F9 -> Ubuntu -> Grub). I can mount any of the Windows partitions under Linux, and the contents appear superficially reasonable, so the partitions have not been totally overwritten. I cannot say more than that.
I'll probably have to re-image the machine from the recovery partition and then reinstall Xubuntu to be able to use Win8. Before I do that, though, I'd like to find out how to avoid damaging the Windows installation, so I don't wind up in the same situation again.
I did run BootRepair a second time: the link is at the top of this message.
I'd really like to get to a state where:
1. booting gets me to Grub by default
2. the Windows items in Grub work.
Alternatively, I can re-image, reinstall Xubuntu, avoid BootRepair, and put up with needing F9 every time I boot.
OBTW, "efibootmgr -n 2000" DOES work: the machine boots to Grub the next time without manual intervention. However, "efibootmgr -o ..." does not work. The command gives no error output, but a subsequent efibootmgr with no operands shows the same boot order as before, and a reboot still won't come up in Grub without F9.
I could hack in a shutdown script to run "efibootmgr -n 2000" on every shutdown of Linux, but that's really ugly and should not be necessary.
One last detail: I did the Xubuntu install with manual partitioning, to put everything except /boot into a encrypted volume group. I doubt that this matters, but thought I should mention it.
Suggestions gratefully accepted.
