I have just installed Ubuntu 12.04 on a laptop with Windows 7 but I don't get to boot from Ubuntu.
First, during the installation I made these partitions (may be too many):
/dev/sda1 FAT32 SYSTEM 200Mb boot (EFI boot, i guess) /dev/sda2 unknown file system 128 Mb msftres (Windows Boot Manager) /dev/sda3 NTFS OS 100 Gb (Windows 7) /dev/sda4 NTFS DATOS 315 Gb (Data partition) /dev/sda5 ext4 28 Gb (/home) /dev/sda8 unknown file system 1 Gb biog_grub (i'm not very sure why i made this one) /dev/sda6 ext4 17 Gb (/ Ubuntu 12.03 installed withou errors aparently) /dev/sda7 linex-swap 2 GB (swap)
I can boot from Windows perfectly. Actually I tried to configure Windows Boot Manager with EasyBCD but it doesn't recognize any boot entry. Anyway, I added an Ubuntu Entry and it configured it automatically.
Now I have boot entries the Windows 7 one that appear to work and the Ubuntu 12.04 that it prompt a "No application found" message.
I re-started from a USB with Ubuntu and tried to fix GRUB from the command-line and with boot-repair. No results.
As far as I understand I have to tell the Windows Boot Manager where my Ubuntu boot loader is.
So I have two problems:
- Actually, I don't know where my Ubuntu boot loader, GRUB or GRUB2 or whatever, is.
- I don't know how to set my Ubuntu entry in Windows Boot Manager. I guess using
BCDedit.exeas EasyBCD didn't show me the entries. Anyway, I don't know what parameters to use.
I read several articles about it but i didn't find out anything useful.
