Unable to boot Windows 7 after mint 17.1 installation

Post by a.humphriesmicallef »

Hi
Problem: when I attempt to load the windows 7 I get the message:
Status: 0cx0000225
Info: The boot selection failed because a required device is inaccessable

I'm running on a Acer Travelmate 8481 - 64 bit
used an installation USB
During installation of linux I ran into trouble during the installation; the first time I tried it, GRUB wouldn't automatically load and would instead go straight to windows
I figured that this was due to the fact linux had been installed in the Logical based partition of my existing C: drive (where all my files and programs are)

Shutdown computer, re-installed Linux using USB - this time, I had cleared out a 15GB section originally dedicated to recovery
Linux installed, but not the switcher (at this point I had not cleared the other partition created by the first installation so the Logical partition had both a linux and switcher on it)

cleared the logical partition of the linus and switcher partitions, re-allocated space back to windows C: drive, cleared out 15GB space again
Re-installed Linux (successfully) in 15GB spot

During the whole -repartitioning process, every once in a while I would get random 1 or 2 MB slices of unallocated memory that I would allocate to nearby partition, so I've re-partitioned every space on my HDD - Linux, Swapper, 100MB SYSTEM RESERVED windows partition, & windows C: containing all files and programs

At this point, tried to go back to windows and encountered the error

Are you able to boot into anything at present?

Also what is on your second drive?

Windows should always be installed first and then linux after. By putting Mint on sda1 you probably need to restore the Windows 7 master boot record.
What I would do is firstly remove the sda1 partition using gparted on your Mint USB running live. Then follow these instructions to restore the Windows 7 master boot record.

If this is successful and you are then able to open windows post back and I will suggest the best way to setup your partitions for Mint.
Good Luck.

The MBR is but a small part of your problem ...

The actual Windows loader code is NOT in the MBR but instead, is in the 100MB partition -- which, if you overwrote it, is now gone.

Restoring the MBR will not restore the windows boot loader. Typically, to do that, you run Startup Repair (from the windows disk) three times, that's right, three times -- which will then rewrite all the boot files and folders.

Not sure if the "boot repair disk" from Sourceforge will solve you problem. Burn the ISO then boot to it and it repairs the GRUB as well as various versions of the Windows loader/boot record. Possibly worth a look? (Worked a treat for me)
