I bought a barely used TC895 with a wiped HDD. It's not a hardware problem as I saw it working prior to purchase.
It won't go into boot menu to boot from either DVD or USB, just tries to boot from HDD then says "please select proper boot device".
What I've tried based on internet advice:
in BIOS set 1st boot device to USB or DVD (tried both neither works)
set a supervisor password
secure boot disabled
boot menu enabled
disabled boot from HDD
F12 on reboot does not bring up boot options (F12 is recognized when I press it because it asks for the supervisor password)
All ACER tech support suggested is to F9 reset BIOS - tried this and doesn't make a difference
Any ideas please, just need it to boot from USB or DVD. Done this to heaps of PCs why is this one so difficult
