I keep getting this error code when I boot my laptop to any kind of Windows-based Preinstall Environment (WinPE) from USB stick: I have tried all the obvious stuff, ike different USB sticks, different booting methods, YUMI, Rufus, Windows DVD Tool, etc. I even checked the .wim file's scratch space in DISM, and it's set to 512MB. My laptop has 8GB of RAM installed. Memtest x86 passes everything fine, so my RAM sticks are good. The laptop in question is an HP Envy m4-1015dx my friend gave me. It boots Linux distros just fine, but halts on any kind of Windows PE loading. I have the boot mode set to Legacy/BIOS. (UEFI mode booting fails too, not even recognizing the USB stick as bootable media, but that's probably it's own issue.) The laptop has the latest BIOS/UEFI update installed. I'm completely at a loss here, I've Google'd this issue to death before coming here, and nothing they recommend works. The computer just acts like there isn't enough RAM, and gives up FOR NO REASON. 8GB should be enough to boot even the largest WinPE images without a hitch, and my ISO files boot fine from Virtual PC's and other machines. Now, having read everything above, is there anything else I can try to get this working?
