My friend had an issue with her windows laptop and she asked me to help. The laptop cannot boot properly anymore so I wanted to reinstall Windows from usb. I tried to restore but it didn't work. Since I have a Mac, most tools to create a bootable USB don't work.
I couldn't use Boot Camp Assist (as most howtos suggest) because it didn't show the option to "burn" an USB on my system and I didn't want to install Xcode hoping to change that. I "burnt" my usb using dd but I couldn't convince the laptop to boot from it. So after some more research I found unetbootin and an howto that suggests to erase the usb and formatting it using fat32 and then "burn" the iso using unetbootin. It ALMOST worked - windows installer starts but then complains about "cannot open d:\sources\install.wim 0x8007000d" (hope this reference helps other come to this question) searching for this I found that this file is bigger than 4GB so FAT32 is not an option. I reformatted the usb on Mac using exFAT and reinstalled the iso using unetbootin - but still no solution When I format the usb with FAT32, I can see a UEFI entry pressing F12 on the Dell during startup - but now that option is not there. I can choose USB in the legacy menu but I just get to a blinking cursor. Ideas? thanks!
Do you have the Windows ISO file? – Biswapriyo – 2018-11-25T09:58:46.420
