[SOLVED] Windows cannot be installed to GPT disk

pCarson92 347 114 September 5, 2012 at 04:33 PM
While trying to Wipe Windows 7 and install Windows 8 on my Zenbook, I have encountered an annoying error message: "Windows cannot be installed to this disk. The selected disk is of the GPT partition style". No other information is given. I am using a 128GB Sandisk SSD and Windows 8 on a bootable flash drive. I have been Googling for an hour but can't find many relevant results. I don't have Windows 7 at all anymore to run diskpart. I do have a GParted Live CD, but not quite sure how to use it.

Also note: There are 3 partitions to the SSD as of now:

Drive 0 Partition 1: SYSTEM 200MB
Drive 0 Partition 2: Blank 105GB
Drive 0 Partition 3: Recovery 10GB

Any help is greatly appreciated, as I need this ASAP for school.

If your SSD is configured as GPT then you have to delete all 3 partitions. That means you will lose your recovery partition if you are ok with that. Then create 1 new one. Windows will recreate the system partition as necessary

I'm right 97% of the time. Who cares about the other 4%

Nevermind, I fixed it. Used Gparted to create a new partition table. Are there going to be any drawbacks using NTFS instead of EFI? The whole file system thing confuses me.

You are talking apples and oranges....

GPT and MBR are partition styles in order to boot windows from GPT your motherboard should support UEFI (EFI-boot vs BIOS-boot) otherwise you should use MBR to boot from. This is probably what you did using Gparted.

NTFS and FAT32, FAT16, exFAT are file systems

So to answer your question..no drawbacks because you would have been using NTFS anyhow most likely.

MBR is what most computers today use and supports 4 primary partitions
GPT supports 128 partitions and is meant for >2TB drives

Thank you. I used Gpart to to create the new partition table like you did and was able to install Windows 7 on what used to be a Windows 8 table with a GPT type partition. nod

But don't you then have to use Legacy mode as the key that was installed in the bios was for Windows 8?

I resolve this problem by deleting ALL the partitions that appear at the installing window popup! You have options to format,refresh, etc..., but you need to delete every partition and then the windows installing setup will create 2 partitions by defaul, one for the GPT table and the other for the OS and you sould be OK!!

I agree that is the easiest way to go instead of dicking around with Gpart, but you mentioned two partitions and GPT in the same sentence and that's not quite how it goes.
If you're installing 7, then it would make only two partitions, but not GPT, on the other hand, if you're installing 8, it would be GPT, but it'll make 3 partitions.

Some bios' don't even have the Legacy option, per se.
The critical change to be made in the bios of a Win 8 machine, is to disable the secure boot.
Some machines might require other settings to be changed, boot order, enabling Legacy, turning off fast boot, etc.
