Grubscreen not showing on single-boot setups - how can I fix this ?
#1
Something I've noticed on our Dell D630 is that when I have a single-boot setup with LL, the laptop boots straight to the Desktop, bypassing the grubscreen. However, this problem is absent with dual-boot setups (either LL/Win or LL/Linux), where the grubscreen shows itself as you'd expect. This no-show of grubscreen, with single-boot setups, also occurs on some of our other machines.

I'm trying LL4.6 as a single-boot setup on the D630: unlike LL3.8, which it whizzes along, it doesn't seem to like LL4.6 (loads of lag on booting). So I've installed the headers & image for the older 4.4 kernel, hoping this will get LL4.6 to work on this 13-year-old machine. However, without the grublist appearing on boot-up, I'm unable to select the 4.4 kernel.  How do I fix this so I can get to select the kernel 4.4 ?

Any help / comments much appreciated ...

2008 - Asus X71Q (2cores) ~ Intel [email protected] - LL4.6/Win8.1 dual-boot, LL works fine with kernel 4.15
2007 - Dell Latitude D630 (2cores) ~ Intel [email protected] - LL4.6, works well with kernel 4.4; 4.15 doesn't work
