Just tried to install Windows 10 on my Laptop. When I tried to select the free partition on my drive it said it couldn't install because on EFI systems it only support GPT and not MBR. WTF? What about dual booting with older systems? I'm not going to reinstall everything because of this. Any ideas? Am I doing sth. wrong? Or are they really big aholes?
I just put it on the stick as I've always done with Windows 8 and older versions. And I selected the stick from my boot menu.
Indeed, I installed my Windows 10 to MBR/UEFI mode. So it's installed to BIOS rather than the hard disk device as it's in the case of GPT. It's running perfectly well without any error. Although, I used Rufus to do that.
If your drive has MBR partition style, you won't be able to install windows in EFI mode. To install in legacy/mbr mode make sure you marked boot partition on your stick as active.
So, partition on boot stick is active. Still the same. Even Set UEFI in Setup to Legacy. Same result. But I remembered that last time i used the stick with a tool to make a UEFI mode Win7 installation. Today i just removed all the files from that stick and extracted the iso to the stick. So is it possible that the USB stick was somehow "marked" to make an UEFI installation by the tool and therefore now only tries to install in UEFI mode? Thanks
format the stick to NTFS and then extract the iso. EFI cannot boot to NTFS, only Fat32. That might solve your problem.
hi, i wonder if one could use dism command to set up windows 10 into MBR partition scheme on C:\ with .wim file extracted into your D:\ the smiley is ": D : \" without spaces
If you have a USB device , i think you can install Windows 10 by USB boot , use Rufus USB or Window 7 USB tool I dont have EFI & GPT too, but when i used USB boot, i can install it normally
I tried to install Ubuntu 14.04 (dual boot) with windows 10, but Ubuntu failed to recognized the windows partition. Any idea?
You can install Windows 10 manually using DISM. Just remember to use BCDBoot when your done. Heck, you can do that on Vista, 7, 8, and 8.1. Personally, I manually create my partition layout via DiskPart, use DISM to install Windows, use BCDBoot to create the primary boot components, then use REAgentC to finish deploying WinRE and a Recovery Image file for Push Button Reset.
