Hey, as the title states I accidentally installed SteamOS with the first option thinking it is going to show me the disk partition that I created for the SteamOS but guess what? It automatically tried to format the whole disk and install the OS.. I immediately powered it off and now it doesn't boot.. Is there any way I can recover my datas and windows 7? Tried to use a Windows 7 Pro Iso but looks like it created 3 logical parititons in like 9,5 GB each and the main partition as 437.1 GB partition 4... I really need those files on the windows I had... Can I just install a fresh Windows 7 iso and recover the files?
