Can't install Win 8.1

[MiguelOliv]

Hi there,

 

I have  WD 1 Tb, that when I installed Win 7 I made a partition of 200 Gb for the windows installation and the other partition for data, backup, etc.

 

My question is, when I tried to install Win 8.1 didn't let me, said that the partition that I wanted to install wasn't GPT and for this reason I couldn't install. For my knowledge I have to erase all the partition of the disk to be able to install Win 8.1 right? Or do I have a way to only modify that partition with GPT and then install win 8.1 and preserve all the data on the second partition of data?

Not to knowledgeable on this, but I always thought you bought a Windows 8.1 update disc. Then it upgrades it for you.

not sure why u have different partitions for generic data. but are u sure u dont have an upgrade disc? ive never used one i just buy the full thing and do a clean install.
you will still have your data in a windows.old folder so try that if you can

I converted a whole drive to gpt before without losing any data. I would recommend you to back up before you do it. But my drive was only one partition so it may be a different process to convert if you have more than 1 partition on a drive (not sure if it acts as one partition in Linux but I think it is because the person had multiple partitions:http://sdnalloh.com/converting-win7-from-mbr-to-gpt/

Hmm I don't like very much upgrading. I prefer installing from scratch. The thing is I don't have extra space to backup and format all the disk and install win 8.1.

Doesn't make me such difference, because Win 7 is great...

Thanks, I'm going to have a close read on the subject and then decide. Most probably is to backup all, and install Win 8.1 like always

I have read the link that you send me, and it's a little elaborated process. If was to upgrade from Vista to 7 I could make the effort, but from 7 to 8.1, I think I'm going to make backup of things and install from scratch like always do. It's more efficient these way!

 

Thanks for the support!
