Information about the machine: Laptop Acer Aspire 4720Z, HD 160 GB, RAM 2GB (old machine).
Aim: Install Ubuntu 16.04 preserving the pre-installed Windows (It is Windows XP, I think)
Hi,
I am trying to install Ubuntu 16.04 in a laptop with Windows. So I created a bootable USB stick. When I try to install Ubuntu the installation produces the following message
gfxboot.c32: not a com32r image
boot:
I searched on the internet and it is ease to work around using the procedure
Press tab
Type 'live'
Press enter
After the installation I restarted the system and I received the following message in my screen:
error: unknown filesystem
grub rescue>
Again I searched on the internet and I found some instructions that hypothetically would fix this problem:
The command
grub rescue> ls
returns
(hd0) (hd0,msdos6) (hd0,msdos5) (hd0,msdos4) (hd0,msdos2) (hd0,msdos1)
The command
ls (hd0,msdos4)/
returns some folders, between them I have boot/, home/, opt/, root/, usr/.
So msdos4 is the partition that I must regard. The next steps occur with no problem:
set prefix=(hd0,4)/boot/grub
set root=(hd0,4)
and the command
ls /
returns the same folders boot/, home/, opt/, root/, usr/, etc. above. But when I try the command
insmod normal
I am informed with the message
error: file not found.
After this command I was supposed to use the command normal, Ubuntu would be loaded and I would install grub2. I searched on the internet about this but I am with difficulties in proceed.
Then I decided to use the bootable USB stick in order to repair the grub or even reinstall Ubuntu. But when I do this I get the message
end kernel panic - not syncing vfs unable to mount root fs on unknown-block(2,0)
I can not boot from USB stick, so I can not repair the grub neither reinstall Ubuntu.
I am not able to move forward in this matter.
Please, any help will be appreciated.
Best regards,
Denis
