Doing that with legit MS media doesn't work - at least not on my Samsung ATIV 7. EVERYONE said use ISO2DISC or Rufus in GPT mode. Seems okay so far, but after this much frustration not ready to claim victory.Īgain, it clearly appears to be a bug to me. I'd already manually created the EFI, msr, and system partitions so all I had to do was delete the other blank partition I'd created for the install and let Windows recreate it. In my attempt to try everything until the stars lined up right or I destroyed the laptop in frustration I burned the 8.1 圆4 Enterprise ISO in Rufus but in MBR UEFI mode, and I left the laptop in UEFI only mode - and it booted. UPDATE - it appears I MAY have a workable solution, though I still consider this to be a firmware bug of some sort. Also, I tried the original MS media in a DVD drive and it fails to boot as well, UNLESS I put it in CSM and UEFI mode. That said I don't expect it to do boot unless it is going to work in MBR mode. No recovery partition because he/she'd wiped it, but recovery media on the way.
MD5's check fine, and they came from our office so I know they're legit. I've tried 8.1 RTM 圆4 iso, 8.1 Volume 圆4 ISO, and 8 圆4 Core iso. Exact Rufus (as well as other programs) settings advised above. I've tried both of the above things FWIW. So what I was wondering is if one of the geniuses here has any idea how I can modify the Acronis recovery media or create similar WinPE media that might actually boot on my laptop. The only thing I can figure is that the way WinPE 5 or 5.1 (whatever it uses) is set up on it agrees with my laptop. ONLY True Image 2014 DOES ACTUALLY BOOT in UEFI mode on my laptop. Paragon, Aomei, Macrium, Lazesoft - all boot media failed. So.I tested several recovery programs we use at work to make sure they'd restore it okay via bootable media. When I'd installed it earlier this week in CSM and MBR mode, and then converted to UEFI it worked fine.
If I set it back to CSM and UEFI I can make a USB boot, but even if I use diskpart to clean the drive and convert to GPT it will fail to install because it detects I didn't boot in UEFI mode. I wanted to put Win 8 on and I have a volume license as well as the OEM key so I burned the ISO (actually 2 different ones) using every method I could find (ImgBurn, Rufus, Iso2Disc, Win7 Download tool, etc.) It became clear that the USB needed to be formatted FAT32 with GPT filesystem, however in UEFI mode it shows the USB but won't allow me to select it - it just flashes. In short, I bought an ATIV 7 whose previous owner had downgraded to Win7. So I've searched, and I've tested, and now I'm about to turn my laptop into a frisbee and never buy a Samsung PC again.
