sorry if my English is not so good.
I have been making a bootable usb stick with both windows 10 and windows seven installation inside it. I prepared the stick and copied the windows installation files from ISOs to the stick. The windows 10 installation files are inside a folder named x86 on the stick like the original iso
I used visual bcd editor to modify the bcd store and added the windows 7 setup entry to it and every thing is perfect. The windows installation files is inside a folder named sources in the stick same as in the original iso.
The problem is :
When I boot the stick and select setup windows 10 I go through the installation process until I get stuck at:
windows installation driver is missing browse to get it from a usb or cd ....)
When I select windows 7 setup I successfully installed windows 7 on vmware without any problem.
BUT....
If I change the name of the folder that contain the windows 7 installation from sources to any other name the windows 10 installation working perfectly.
If I edit the bcd to take the installation for windows 7 setup from the new folder name it give me the same error as windows 10 setup (windows 7 setup missing drivers...) but now windows 10 setup worked perfectly .
What should I do to make them both working?
I think this boils down to that you are doing something that MS hasn't prepared for: Having the installation packages of two operating systems in the same partition of a media (I hope I did understand right how you have put the installation image contents on the USB stick). It probably would work if you had separate partitions on the USB stick for the installers, but I guess there might be other issues with that since USB drives rarely have multiple partitions (booting to 2nd partition might not work)... (and I can't anyway help you with how to set up such partitions) – zagrimsan – 2015-11-24T14:13:59.737
yah you are right but i still think that there is a way to do it (i think that i have to edit something inside the boot.wim to find the right path of the install.esd not sure yet ) any way thank you so much for your comment... – Feras albarbary – 2015-11-24T14:29:07.307
