thinkpad x220: ," unsupported hardware error" during install, black screen after install

[cacao...@tutanota.com]

During qubes installation, the wizard trigger an "unsupported hardware error" on my x220, saying that VT-d is not enable, which is weird because it is in the BIOS settings. I tried to continue with the install anyway, but when I boot on qubes all I get is a black screen.

Is very weird, because this is actually a reinstall. I had qubes installed on exactly the same hardware just a few month ago.

I have tried to install both  R4.0.3 and R4.0, and same result.

Anyone had similar issue or could give a clue on how I could solve this. ?

Hi. I have had some different symptoms with different distros on different computers. In one set of cases of installing a distribution of Linux on a USB key it does strange things. A live version on a USB key will start run as though it is happy. Then when I install off the same USB key, the result on the hard drive will give an error message. When I look up the error message it is the boot is not correct. Some fellow said something about copying three files into boot sector. Since I have not the slightest idea of which three files from what directory. That was not much help. I once put Mint Linux on a USB key. It worked. I installed it onto aa Samsung SSD onto a 2009 Mac Book Pro. MBP started functioned all right. When I tried to Shut Down the process went on for twenty minutes and I had to hard Power Off it off and the SSD would not boot. I finally put a spinning hard drive in MBP to get it to allow me to install Linux on it. I put Ubuntu on the USB key. When I boot up the USB key, I see a message, Mint Linux, then it will start up Ubuntu. I believe programs which install Linux distributions don’t alway clear off old boot sectors and write information fresh onto boot sector. One needs to clear off everything on flash drive, including boot sector. And write Qubes on flash. Like wise I am suspicious of distributions auto installers as they seem to not redo boot sectors. Probably some part of allowing multiple distros to be on same drive. I also feel some auto installers will give more functional results if an Ethernet Cable is plugged in through out the distribution install process.

Clobbering boot sectors on either a USB key or a drive seems to require efforts with different software. Boot Sectors are not always so get rid of.

Not sure if this is how the install went wrong. Please let us know how you fixed it.

Another work around is to burn the Qubes iso onto a DVD. Boot from that DVD and install. Seems to work every time. I get an error message but the resulting Linux seems to work. I am not satisfied. I will work on this some more next week.
