Ok Greg I am just a bit of an overkill sort I suppose

Many thanks for the help guys. I assigned a drive letter to the D: partition and backed up my files.

I took Greg's advice and deleted the recovery partition as he says there's no real point in keeping an inferior install.

Now the next problem. I created a bootable UEFI Windows 7 install USB but it goes to BSOD just after the "Copying Windows files...."

The post at the bottom of this LINK shows other people having the same problem and I have tried what it says but it doesn't seem to be working.

Did you use only Option One from UEFI Bootable USB Flash Drive - Create in Windows which is the only method to format stick for UEFI install which always works?

Then delete all partitions after booting the installer as a UEFI device, so if necessary the installer can format it GPT. UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with

If it still fails we may need to look at EFI settings In BIOS. Was the previous install EFI? What are the CSM, Legacy BIOS, Secure Boot settings chosen and other choices offered in BIOS setup? Pictures can help, attached using paper clip in reply box.

Yes I used Option One and deleted all partitions after booting as a UEFI device and it has gone to the BSOD every time at the exact same place on the install.

The previous install was an EFI, you can see from the pic I uploaded that there was an EFI partition.

Just to clarify, here's what I have done up to now

Originally I only deleted the partition that Windows 7 was installed on and left the other partitions, as I had backed up some files onto one of them. I used the Windows 7 USB-DVD Download Tool and it installed Windows 7 no problem that way.
I then couldn't access the partition that had the backup files on it, so I assigned a drive letter to that partition and backed up the files to an external HD.

After that I decided I'd go from scratch and follow the
UEFI (Unified Extensible Firmware Interface) - Install Windows 7 with - Windows 7 Forums and that's where I ran into problems.

UEFI installs are a bit tricky - for some reason, USB install media MUST be formatted FAT32.

If you created the USB using the Windows 7 DVD/USB download tool, then that is a problem for UEFI installs. The tool defaults to an NTFS format on the USB.

The easiest resolution is to create a DVD install disc (the UDF file system does not interfere with the UEFI install).

If you want to use a USB to install Windows 7 with UEFI, you have to pay attention to the minutiae and links in tutorials.

I already mentioned FAT32, but I also want to note that I'm not sure if the USB must be formatted as GPT partition scheme for UEFI computer. MBR partition scheme for UEFI computer might be fine because you can't partition the USB device anyway. The file system, not the partitioning scheme is what I believe is important.

That being said, I would first follow the tutorial as written, then if the machine still has issues, try recreating the install media again, changing the partitioning scheme - it probably won't change anything but who knows.

Two specific areas that I would investigate:
Option Two (Acer): Secure Boot - Enable or Disable in UEFI
Option One: UEFI Bootable USB Flash Drive - Create in Windows

I'll reiterate that the easiest method is to just create the install media on a DVD - this avoids all of the caveats associated with UEFI USB install media.

Good luck,

Bill

Back up your files externally and delete all partitions during the booted install.

If that fails, enter BIOS setup and report back what are the settings choices for UEFI, CSM, Legacy BIOS, and Secure Boot. Pictures would help. To install Win7 it normally it may require some level of Legacy or CSM, UEFI first on any boot selections, Secure Boot off if it's present.

There are none of these choices on the bios.

Do you have UEFI Boot choices in BIOS Boot menu? How did you install to UEFI previously as shown in screenshot?

The Windows Download tool will not write a UEFI capable flash stick. It must be done using Option One in UEFI Bootable USB Flash Drive - Create in Windows

The screenshot was taken after I deleted the factory installed Windows partition only, this allowed me to Reinstall Windows without booting into UEFI. I then wanted to do the UEFI install so I deleted all partitions and this is where I keep getting the install problem leading to BSOD.

I have tried to install with a UEFI Bootable USB Flash using Option One and it's not happening.

So confused?!
