While attempting to install deepin linux onto my new netbook, I worked myself into a corner that I do not know how to escape.
1) I loaded the deepin installer onto my USB stick as per instructions, no problems here.
2) I convinced my PC to boot to the USB (W8 was a pain about it, obviously).
3) I installed deepin to my eMMC, thus overwriting W8. Here the trouble began. When I rebooted (w/o the USB), Windows recovery kicked in and tried to fix W8, clearly failing as I had made no backups.
4) So I overwrote that partition as well, thinking it would boot to one, and I'd then delete the other.
5) When I rebooted, again w/o USB, I got the following message:
Intel UNDI, PXE-2.1 (build 083) //copy right and patent bits Realtek PCIe GBE Family Controller Series v2.59 (01/13/14) PXE-E61: Media test failure, check cable PXE-M0F: Exiting PXE ROM. No bootable device -- insert boot disk and press any key
In fiddling with the BIOS I turned on Legacy Mode to stop UEFI from trying to restore W8.
6) Inserting the USB and sending a key-strike only repeated the above message.
7) So I rebooted with the USB plugged in and attempted to enter BIOS through that, but did not manage. I tried F11, F10, F11, F12, and Escape. It only delayed the launch of the deepin install programme.
8) I know not how to reset CMOS on netbooks. I tried removing the battery and holding the power button for a while, but that didn't do the trick.
The Netbook is an Acer ES1-111, which does not have a CMOS cell.
