[SOLVED] Lite hangs at boot I know what it is - USB KVM switch

[DLX]

Keep getting above error trying to post  :-\

I looked about found other with same problem not found a solution for this. I'm not pretending to know what I'm doing with Linux. On boot computer hangs I get blue screen with text I pick top one then I get a black screen with a flashing cursors.

This keeps happening each time I boot was hoping on update would fix this.
How I get round this Boot get blue screen with text I pick top one then pull USB cable out back of computer then I get next screen image grey with feather and back bar loading at bottom once bar bar is starting to load I pug USB back in.

One booted in the keyboard works fine through the KVM, I have had a look at BIOS the boot order see about putting it 1st in list.

I also looked at keyboard setting can't see anything there.

I will look at Gold finger post about pressing left shift Link removed

pci  noacpi to the kernel boot parameters allowed me to boot without disconnecting the usb kvm.

Someone post this but I don't have a clue if it fixes problem or how.

Thanks
