My Acer Aspire One has 1MB ram and a 16GB SSD. At the moment I generally run Ubuntu from an external USB key leaving the original Linpus on the SSD but strangely,if I switch on and press the F12 key (Boot options) on the BIOS screen it locks up. If I switch off then back on again the F12 key works fine. Always seems to work on the second attempt. Anyone else experience a problem? Geffers
