I have run into this same exact problem with Windows 8 and Windows 10. I used Rufus to create a bootable thumb drive. My computer boots from the thumb drive just fine and the Windows setup runs normally, until I get to the screen where I select which hard drive I want to install Windows on. Then I get an error message which says: "Cannot create a new partition or find an existing partition" BUT, if if take that same exact ISO and burn it onto a DVD, it installs just fine. No errors, everything works. What am I doing wrong?
I used "windows 7 usb/dvd download tool" downloaded from the official microsoft site (select win10.iso etc) and it works fine
Rufus isn't 100% compatible for real MS ISO's! For real MS ISO's use Microsoft's Windows 7 USB/DVD Download Tool only and you'll not face such problems.
On the contrary, it is. On the other hand, Windows 7 USB/DVD Download Tool always formats the USB drive as NTFS, which can't be used for UEFI booting without supplying additional NTFS driver. Check carefully, my laptop is from 2012 & it supports UEFI booting.
Sorry Tito, nearly ALL MS ISO's I was try to use with created USB Sticks by Rufus FAILED! Never had any fail with MS 's own Tool with MS ISO's! Rufus may works for some original MS ISO's but ALL! About the UEFI, you're right. But the MS tool was build for Windows 7 at those time and MS didn't has done a new one AFAIK!
I used the Microsoft tool and still had the same problem. "Cannot create a new partition or find an existing partition". But if I burn the ISO to a DVD then it install fine with no problem. Oh well. I installed Win 10 from a DVD and it sucks just as bad as Win 8. So I just went back to Win 7.
