Hi all! Having a bit of trouble with an Ubuntu/Windows 8 dual boot, would greatly appreciate some help.

For background info, the machine is an Asus F-551-M which came with Windows 8 pre-installed (I then added Ubuntu later, which worked reasonably happily for a short time before problems started - it didn't bother me too much at the time though because I never used Windows).

I've had problems with Windows 8 dual-booting with Ubuntu for a while so I tried starting again from scratch. I removed (using OS-Uninstaller) my Windows partition and completely reinstalled. Everything was OK and I was able to access Windows, but not Ubuntu (even by the long route you should be able to when Windows hogs the boot). I then used the Boot Repair tool within Ubuntu Live to fix this, which returned Grub and I was momentarily pretty happy.

However, I now have similar problems to those I had previously and am hoping there's something fairly simple I can do to sort it out.

Now when I get to the Grub menu, I have the following boot options (numbered for easy reference):

1. Ubuntu
2. Advanced Options for Ubuntu
3. Windows UEFI bootmgfw.efi
4. Windows Boot UEFI loader
5. EFI/Ubuntu/MokManager.efi
6. Windows Boot Manager (on dev/sda2)
7. System Setup

The Ubuntu boot works without a problem. I haven't tried 2 as it's presumably irrelevant to determining the problem.

- 3 goes into "preparing automatic repair" then "Automatic Repair
couldn't repair your PC"
- 4 leaves me with a black background and the blue window silhouette under which dots eternally circle
- 5 leads to "SHIM KEY MANAGEMENT" "Press any key to continue", after which I get three options "Continue Boot", "Enroll key from disk" and "Enroll
hash from disk".
- 6 continues to "preparing automatic repair" then "Diagnosing your PC" then "checking disk for errors - this might take over an hour" then "AUTOMATIC REPAIR" then leaves me a message "Logfile: C:\\Windows\System32\Logfiles\Srt\SrtTrail.txt" before giving me the options "Shut Down" or "Advanced Options" (which include all the standard options "Continue" (which goes back to grub), "Use a device", "Troubleshoot" and "Turn off").
- 7 Leads to my BIOS

I went in with GParted (within Ubuntu Live USB) again to check the partitions and they are as follows:

- SDA1 Fat32 boot
- SDA2 ext4
- unallocated
- SDA4 unknown msftres
- SDA5 ntfs msftdata
- SDA6 linux-swap
- unallocated
- SDB1 fat43 /cdrom boot/lba (the Ubuntu live USB presumably)

In addition, I noted the Boot Repair log when I made the adjustments just before the Windows boot problem:

Any help you could give would be much appreciated as I will need Windows for work soon. Thanks in advance.

A
just delete all partitions make sure you transfer you data if any in external hdd
install windows as always

well i don't remember all steps now, but this works, tried it on my system it worked...


just while installing ubunut
click install 3rd party software(imp)
click next
click something else (there are options like along side windows, at bottom there is something else option) (imp)
click next
probably it will take you to the HDD part (imp)

while you are in the hard disk partition
give 1mb to boot the would be and option in drop down list(drop down list of file system), saving something, there would be boot return in that option
the (in not the directly start with following steps)
make your boot folder assign any amount of space...

the (in not the directly start with following steps)
make your boot folder assign any amount of space (i did 20gb for this, you can reduce it as per you like) (there is drop down list there below the drop down list which is used for selection file system by default it is set to ext4)
the your root (20gb again)
then your home (20gb again)
the some space(4gb, keep it 4gb only) and mark it as swap space...

make every partition as ext4 only


hope this solves your problem
