johnhc Posted August 3, 2012 Share Posted August 3, 2012 Bumbastik, I do not know about WinPE 4.0 but I have created a 3.0 USB stick (nothing special done) that I can boot in both old BIOS mode and UEFI mode. I use it to start a flat install (from HDD). UEFI mode allows the creation of a GPT formatted disk. Enjoy, John. Link to comment Share on other sites More sharing options...

johnhc Posted August 5, 2012 Share Posted August 5, 2012 Bumbastik, sorry, I do not know what a "uefi structure" is, so I cannot help you. Enjoy, John. Link to comment Share on other sites More sharing options...
Tripredacus Posted August 6, 2012 Share Posted August 6, 2012 My question is a bit different , I'm trying to build an usbkey ( fat\fat32) with uefi structure and WinPe4I'm not sure you can boot a FAT32 volume in UEFI mode. Link to comment Share on other sites More sharing options...
cdob Posted August 6, 2012 Share Posted August 6, 2012 (edited) build an usbkey ( fat\fat32) with uefi structure and WinPe4It's supported by default.

johnhc Posted August 6, 2012 Share Posted August 6, 2012 (edited) Tripredacus, as I stated above, I can boot my WinPE 3.0 in legacy or UEFI BIOS. I just checked again and the USB stick is FAT32. Enjoy, John.EDIT: Bumbastik, In my comments above I am discussing results with 64 bit WinPE 3.0. I also have a 32 bit USB stick and it will not boot in UEFI mode.

Tripredacus Posted August 7, 2012 Share Posted August 7, 2012 @ Tripredacus boot from fat /fat32 should be a UEFI spec /requirement Should be, but won't. Spec only supports 64bit capable "things." But... that's just official support. No one can say it won't work which in this case it sounds like it does. Link to comment Share on other sites More sharing options...
Bumbastik Posted August 7, 2012 Author Share Posted August 7, 2012 (edited) Hello , i will try and we will clarify all dubts ...as usual Official info should be file system fat or fat32 and WinPe x64 version Bye AnyB Edited August 7, 2012 by Bumbastik Link to comment Share on other sites More sharing options...
Bumbastik Posted August 8, 2012 Author Share Posted August 8, 2012 Hello Guys , all the specs are confirmed UsbKey -> Fat32 +WinPe 4 x64 -> Works fine UsbKey -> Fat32 +WinPe 4 x32-> Doesn't work UsbKey -> NTFS +WinPe 4 x32-> Doesn't work UsbKey -> NTFS +WinPe 4 x64-> Doesn't work How to build WinPe 4 Uefi mode - start with admin privilege DandISetEnv.bat- run copype.cmd amdx64 x\yourforlder- mount -> customize and commit your boot.wim present inside media/sources/boot.wim - copy ALL the content of the media folder on the root of your usb key Fat 32 That 's all ...enjoy BRsAnyB.

johnhc Posted August 9, 2012 Share Posted August 9, 2012 Found this here:Booting X86 WINPE 4.0 requires that the UEFI be at least 2.3.1.The question then becomes, how to determine if your BIOS is UEFI 2.3.1 compliant? I suspect most current ones are not since this UEFI specification was released in June 2012. In the WinPE 4.0 files is MakeWinPEMedia.cmd which formats and copies the necesdsary files to the USB stick (/ufd switch). It formats the stick in FAT32 format using DiskPart. Enjoy, John.

Tripredacus Posted August 10, 2012 Share Posted August 10, 2012 Found this here:Booting X86 WINPE 4.0 requires that the UEFI be at least 2.3.1.The question then becomes, how to determine if your BIOS is UEFI 2.3.1 compliant? I suspect most current ones are not since this UEFI specification was released in June 2012. UEFI 2.3.1 started showing up early this year, nevermind the publish date on that document. There are a few ways I have found so far.1. In the BIOS, there is an option to enable UEFI boot2. The motherboard spec sheet mentions support for "Fast Boot"All Intel boards (look at board rev/AA number) on this list have it:http://www.intel.com/support/motherboards/desktop/sb/CS-033076.htmNote the exceptions below. Anything newer from Intel have it, such as X79, 77 chipsets, but some of their "embedded" type systems, do not have it such as the D2700MUD. You'd have to look at the ProductSpec PDFs to find this info.Other ones its tough. All the new Compal, Pegatron and ASI notebooks/Ultrabooks have it, as do the A75 MSI AMD boards, but this information is even harder to find. The only reason I know those is because I've gotten in the habit of asking. Link to comment Share on other sites More sharing options...
kyor Posted August 14, 2012 Share Posted August 14, 2012 Unfortunately it does only work on fat/fat32. I have tested exFat but this doesn't work, too.So my install.wim file can't be greater than 4 GB due to FAT32 limitation Link to comment Share on other sites More sharing options...
