I'm having trouble with a dual boot, I can't get Ubuntu to boot properly, although the install itself works fine (see below).
I've just installed Ubuntu Gnome 13.04 to dual boot alongside Windows 7. Computer is an 64 bit i7, 8GB RAM.
As this is my uni computer I decided to add a second hard drive (WD3200AVJS) in order to leave the Windows 7 drive alone entirely. I followed the directions given here linuxbsdos.com - dual-boot ubuntu...windows-7...2-hard-drives/
Upon completing the installation I changed the bios settings to boot from the second hard drive first. However the computer fails to display the grub boot options, after turning ont he machine i get the brief boot splash screen (offering the options to edit bios, go to boot menu etc), and then an empty black screen with a flashing cursor. Nothing further happens.
If I change the bios to boot from the first drive, Windows boots fine.
I have a USB stick on which I have a full install of Lubuntu (ie it's not a LiveCD but a regular install), if I boot that I can use the grub menu it shows to boot Ubuntu installed on the 2nd HD, and I can then eject the usb stick fine - so the install itself works, it just appear to be a boot problem.
I have Windows on /sda
I have 200MB /boot partition on /sdb1
I have 40GB / partition on /sdb5 (am on a different computer right now, but i think it's sdb5, it's def on /sdb)
I have 270GB /home partition on /sdb6 (as above)
and i have an 8GB swap partition also on /sdb_something
I did the install from a bootable USB made from Ubuntu Gnome iso. I don't think it's the cause of the problem, but when I did the install, the USB stick was on /sdb, optical drive on /sdc, so the hard drive onto which I installed (which is now /sdb) was at the time /sdd. I ensured I selected /sdd as the target for the bootloader.
After booting Ubuntu (on /sdb) using the Lubuntu USB stick I have reinstalled grub (so now specifying /sdb as the target) and grub-update, and it's made no difference.
I have run gparted and set the boot flag on /sdb1. No difference.
I won't be at the PC until monday morning, but I was hoping that I could go into Uni with a clear idea of the steps I should take to try and identify or fix the problem, or what further information I should provide (now, or on Monday depending upon what is needed).
It's fortunate I can work around this, but I'd be very grateful for any suggestions as I don't really want to spend the next 3 years using a USB stick to boot my computer!
Thanks in advance
