I used to run Ubuntu on my mac but needed Windows so decided to reinstall El Capitan and use bootcamp. One major problem I always faced was that my mac didn't accept any startup key combinations, making everything much more difficult. I have a wired Windows keyboard, which i've tried on all 5 usb ports and with all possible combinations.
Bootcamp didn't let me use an .iso file to make the windows partition and i didn't have a windows DVD so I tricked it by mounting my Windows iso with Deamon Tools. Bootcamp created a partition and booted into a "No operating system found" screen. The mac did't accept any of my USBs so I finnaly found a Windows XP CD that I had and inserted it. It installed XP, so my initial plan was to upgrade, one OS at a time, to Windows 10, but the XP was 32-bit and didn't allow me to install a 64-bit Vista Upgrade. I still couldn't boot any USB installers so my only option was installing from within the OS.
Now finally I found a Windows 7 DVD, but Windows XP couldn't upgrade from it, so my only option was to get back to the "No operating system found" screen which I stupidly tried by destroying the Windows XP system.
After a reboot, the system still detected XP, just couldn't boot from it. No CDs/DVDs are being detected either.
So to recap, the system only boots to the Windows partition, which has a corrupted Windows XP that won't boot. I am unable to access the Startup Manage. I'm able to boot into Refind from a USB, but only after first removing the Hard Drive.
My assumed possible solutions:
- Find a way to boot to Recovery or Startup Manager.
- Find a way to Wipe the Windows partition so that it boots to El Capitan.
