I've just started to run a clean re-installation of W10Pro64 on my laptop but was stopped when a message came up on screen which said "... Windows cannot be installed to this disk. The selected disk (Drive 0 Unallocated Space .. Total 465.2GB .. Free 465.2GB) is of the GPT partition style".
I don't know what GPT is but I'm unable to get past this to continue with this re-installation.
I would be very grateful for any help please.
Michael.
What are you booting the computer from, a USB flash drive or DVD? How did you create that USB flash drive or DVD?
Thanks for replying ... it's a DVD ...
When you are booting the computer from the DVD, make sure you are selecting the UEFI DVD option and not just the plain DVD option. The computer must boot from the installation media in UEFI mode. It is currently booting the DVD in legacy BIOS (or CSM) mode. If the computer cannot boot the DVD in UEFI mode, then you will have to make a Windows 10 installation USB flash drive and boot from that in UEFI mode.
Well, I guess my problem has been solved ... thanks to you.
I shut the laptop down, fired it up again and went into the BIOS and the only choice I could see relating to UEFI was "BOTH" so I chose that followed by 'SAVE & EXIT' and this thriggered the W10 installation.
This has now been completed and only leaves me to sort out the loads of settings as well as install a few programmes.
Thank you very much for your help ... I've learnt something today ... very much appreciated.
Regards ... Michael
