    @amg11901
    You do not have any LInux. Boot-Repair is more for LInux, but will make minor fixes to boot lloader or move boot flag.
    You may need chkdsk or other Windows repairs from your Windows repairCD.

    Question Dual Boot of Windows 8/Ubuntu 12.10 fails. Either one works but not both!

    Hello, I have Ubuntu 12.10 Secure Remix and Windows 8 installed in a dual boot (using Secure boot).

    When I first installed and started the computer it would give me a message about 'Access denied' when trying to start Grub. Windows would then start.

    After Googling for a while I ran boot-repair from a USB key with secure remix on it, clicked advanced options and clicked 'Secure Boot' box in grub options and clicked apply. Now the computer restarted, Grub worked and I could boot Ubuntu in Secure Boot, but Windows would not boot from Grub.

    I ran boot-repair again and this time clicked 'Recommended repair'. Now when I rebooted I was in my original situation with the 'Access denied' message when it tried to start Grub, Windows then booted.

    Now I have run the advanced repair (only change I made was to click the 'Secure Boot' box) again (so I can get into Ubuntu, which I need to use to do my work) but none of the Windows entries can boot once again.

    My current Boot-Info URL (created in Ubuntu in Secure Boot, while Windows cannot boot) is http://paste.ubuntu.com/1618203/

    I appreciate any help you can give me to get Windows to boot.

    Cheers

    May be best to turn secure boot off.
    Also turn off fast boot as with some systems you can only get into UEFI menu from Windows with it on.

    Boot-Repair will create backup Windows boot files and create boot entries to those. Are you booting from the entries in 25_custom not the os_prober which still has a bug?

    grub2's os-prober creates wrong style (BIOS) chain boot entry
    https://bugs.launchpad.net/ubuntu/+s...2/+bug/1024383
    Type of entry that does not work:
    'Windows ...) (on /dev/sdXY)'

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    I turned off Secure Boot (you can't do this directly in my Bios, you just have to select 'Legacy Support (UEFI First)' rather than just 'UEFI' in the boot order menu. Now on another page of the bios it says 'Secure Boot - Disabled' or similar.
    There is no option to turn off fast boot in bios, so I couldn't do this.

    I rebooted ('ubuntu' is the top of my boot order in bios) and a black screen shows for around half a second saying 'Secure Boot disabled'. Then Grub comes up. Now the 25_custom boot entry for Windows boot entry boots Windows. Ubuntu also boots correctly from Grub.

    So, now I know Windows can boot in Secure Boot (without Grub) from when I repaired with 'Recommended repair' and it booted after failing to load Grub. I know Ubuntu can boot in Secure Boot when I turn it on, but then the Windows entries in Grub (which work with Secure Boot turned off) now don't work.

    Secure boot seems like a good idea and I'd like to use it. I'm not so bothered about Ubuntu running without it but Windows (which I don't know anywhere near as well as Linux) and is targeted by attacks I don't feel as comfortable about.

    1. Any idea's why the Windows entries don't work when Secure Boot is turned on?

    2. Do you know about the progress of Secure Boot support in the version of Ubuntu currently being developed? Is it improving?

    Thanks

    They are still making improvements to grub working with UEFI. But it seems to be complex and each of about 4 or so vendors of UEFI to computer manufacturers each have bugs and then the customization for each vendor have added other issues.

    One example, other Lenovo's have worked.
    Lenovo ThinkCentre M92p only boots Windows or Redhat.

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    Hey guys, i am supposed to post to this thread when i cant fix my problem with boot-repair, so here we go:

    I've bought a Packard Bell PC with Windows 8 preinstalled, 1 hard drive (500GB), 8 GB RAM. Since I don't want to use Windows I grabbed the Ubuntu 12.10 Live-CD and installed it right over any preexisting system. The install dialogue said that it would erase any existing data on the hard drive. Installations went fine, disk checks went fine, but the system does not boot.

    Right after the packard bell logo the following error message appears: "no boot disk detected or disk has failed". I tried boot-repair several times, reinstalled grub, reinstalled Ubuntu, wiped the hard drive, nothing changes. What can I do to fix this problem?

    This is the boot-repair report for my system: http://paste.ubuntu.com/1632516/

    I appreciate your help.

    Daniel

    Hi Daniel,

    disable SecureBoot in your BIOS, then try the Recommended Repair again.
    If still not good, disable UEFI in the BIOS, use Gparted to format the disk in MsDos, and reinstall Ubuntu.

    Whooooooo! Awesome job!

    Oh wow, you also fixed x11vnc for me.

    Been broken since the update to 12.10 and now its working great again.

    Update: "ipv6.disable=1" is what killed x11vnc. Not sure why I never double checked that.

    Well cfq got turned off and ipv6 got turned back on. Whoops!

    Thankfully I take detailed notes of changes I made. hehe

    Oct 18th 2011: Changed I/O Scheduler for sdb (RAID) to [cfq] (Completely Fair Queuing):

    Change:

    1.) echo cfq | sudo tee /sys/block/sdb/queue/scheduler

    2.) sudo gedit /etc/default/grub, GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 quiet splash elevator=cfq"

    3.) sudo update-grub

    Verify: cat /sys/block/sdb/queue/scheduler

    Re: [Boot-Repair] Graphical tool to repair the PC boot in 1 click!

    Hey YannBuntu, disabling SecureBot and running boot-repair again did the trick for an unencrypted Ubuntu 12.10. Thanks a lot for that! (Do you or boot-repair have Flattr?)

    However, I would like to encrypt my system. I reinstalled Ubuntu with the encryption option and repeated the same steps on the now encrypted system. Grub is running then and shows the option to boot Ubuntu as well, but dies afterwards ("Busy Box, gave up waiting for root device"). As far as I know the preboot authentication is missing. Do you have an advice for this issue?

    This is the report for the enrypted Ubuntu: http://paste.ubuntu.com/1633502/

    I was pointed here by boot-repair after it didn't fix the problem I was having. I am running Windows 7 at the moment and used a cd to install Ubuntu 12.04.1 Desktop i386. I chose the install inside Windows option. I'm not sure if it didn't install correctly, or my problem is just a GRUB thing.
    Here's my report: http://paste.ubuntu.com/1633917/
    Thanks for your time!
