Jan 12, 2016 at 17:10 comment added LJD200 Oh sorry! I only just noticed that you updated this answer. When I clean-installed I didn't delete the OneKey recovery and OEM partitions but could these have been deleted too? Please update your answer with these details including the loss of ability of being able to restore to default image using OneKey Recovery (sorry to be picky but just want to make sure that all the info is there for others!)

Tidied everything up with information contained in comments.
Dec 29, 2015 at 17:57 comment added LJD200 Sure could you add some of the details that you said in the comments please, especially about Windows Setup creating the necessary partitions including EFI ones?
Dec 29, 2015 at 14:02 comment added David That's good, I always hold my breath on these things even when I have done them a million times before, there is always that one time it doesn't. Could you mark the question as accepted if my solution has worked for you? Thanks.
Dec 29, 2015 at 13:14 comment added LJD200 I deleted all the partitions except the Lenovo recovery and OEM ones in Windows Setup. There was also a Microsoft System Reserved partition that wasn't listed in Disk Management. I also deleted this and then told Windows to install in the unallocated space, which it did. The whole operation went very smoothly.
Dec 27, 2015 at 18:35 comment added LJD200 Unfortunately, I do not have another hard disk I can use but I've backed up the current hard disk using Clonezilla and I will remove everything but the recovery partitions. Thanks for the help. I'll report back with the results.

Dec 27, 2015 at 16:44 comment added David The system backup should be able to make your recovery media. My advice, though, is to do what I do, which is to open your computer and replace the hard drive with a new (blank) one. That way, if the install does not work, then all you have to do is just put your 'old' hard drive back into your computer, and everything is as it was before. As for the EFI partitions, from my experience is that Windows just creates new ones.
Dec 27, 2015 at 13:10 comment added LJD200 Thanks for the answer. I've updated the question with additional information about trying to create recovery media. Is it safe to wipe even the EFI partition? I've read on various sites that deleting this removes the PC's ability to boot.
Dec 27, 2015 at 13:06 comment added David This Lenovo webpage forums.lenovo.com/t5/Welcome-FAQs-Knowledge-Base/… indicates that you can use Onekey to create recover media.
