Hey guys, I just added the ei.cfg file into my original MSDN ISO by UltraISO, saved the modification and burned the ISO to DVD disc afterwards, but now I discovered that it didn't give me an option to boot from EFI mode. only legacy mode works. How can I fix this? any suggestion? Thanks...
wat do u mean... ei.cfg was never ment to change the boot type from legacy to EFI... it was just to skip the product key installation (off course for time being... u have to install it later either in oobe or after complete install) and help choose the required edition...
@adit123tya of course I know what's ei.cfg used for....I just put it into original ISO without any other change. All I want to do is boot from EFI Mode with the modified ISO to install my clean OS on GPT disk.
Sorry, i have problem with efi mode. My bootscreen (in the windows logo), it's display only 1024x768 resolution, at metro ui and deskop is normal (1366x768) But at legacy mode, all right, in the windows logo and deskop, metro ui, all display 1366x768 ? what reason ?
Read carefully till page two then you will know why: forums.mydigitallife.net/threads/39726-Install-Win-8-on-VMware-with-EFI
ist of all... all of that is for VMware and not physical pc... second thing for me I didn't do any of that... but still my pc is GPT parted and boots through EFI accept that intel yet has to confirm that my mobo supports secure boot
I have the same issue after following threads:" Create a Windows 8 Pro with media center iso only", my dvd installation can not boot as uefi boot and can not install in gpt partition
Here is a tip for those wanting to do an EFI installation. DO NOT use PowerISO to make your final ISO image. It destroys the EFI boot record so when you make a DVD, it won't boot via EFI. Only UltraISO 9.53 (or later) will preserve the EFI boot record so the resulting DVD will boot properly via EFI.
You're right, I've resolved my problem with the latest UltraISO. everything works fine now. So, Thank you guys.
I don't understand y u guys use third party tools to create a bootable iso of win 8... u can always use the Oscdimg that comes with Windows ADK
I just want to do some change in the bootable ISO. so use 3rd party tool should be the best way to do this.
I don't think so extract the files from iso to a folder and when editing is complete use the oscdimg... commandline true but its for sure it doesnot mess with bootsector of iso
I like using USB. once it is bootable, you can edit add etc without having to do any saving or creating the iso again.
