For the past couple of days I was experimenting with Ubuntu. I am running Ubuntu 14 (BIOS) on a Dell xps 15Z. I used a USB drive to install ubuntu on this system (HP formatting tool & YUMI) however since a failed a try in installing WIN 7 OEM via usb, this system does not boot with live USB anymore: " Operating system not found."
I tried to remake the usb via another laptop running windows, the usb works on that laptop but not on the this one running ubuntu; Then I made a live usb using "Startup Disk Creator", which still does not work on this laptop.
Any ideas what is the cause and how I can fix it?
p.s: I do not have CD/DVD drive on this laptop.
Thanks in advance
Boot from other devices). Anyway I would try pressing F12 after power on (F12 is common key for
Boot menu) and pointing at Your USB drive (must be shown there to be booted). Because
Operating system not found.rather says about HDD not the USB.
"Access to the BIOS, and change disk support from UEFI to LEGACY , and then your USB-stick will be recognized".
