Comment 11 for bug 1053670

Daniel,
It regretted to inform you email on the above subject is no use for the
following reasons:

I am newbie to ubuntu and linux. I use WinXP most of time.
Since ubuntu 12.10 has been crashed and just now has been re-installed
from scratch.

 *Reason*:Trying to install ubuntu 12.04(for the purpose of Ocropus Project
for which python 2.7.3 required -works fine - whereas in ubuntu 12.10
failed to work) as a result entire OS winxp and ubuntu 12.10 crashed. In
order to recovery/restore to original position - I re-installed ubuntu
12.10. Now I am able to boot the both OS viz winxp(*which is important for
me*) as well as ubuntu 12.10.

*how problem arised*: I had downloaded both versions of ubuntu
12.04(64bit) and also 12.04(without 64bit) burned CD/RW - but failed to
install and crashed - due error at sector (where I dont know - displayed in
light green color on the monitor) Again I tried using another burned
CD/RW also failed.
Now again as a final attempt I am re-downloading ubuntu 12.04(i386.iso) and
waiting for completion. If this also fails, I am thinking install old
version 10.10
and then upgrade to 12.04.
It appears that iso of ubuntu 12.04 in the website are corrupted? Now I am
perplexed and afraid to use ubuntu of future version - lest I loose winXp
and data etc. unless there is ubuntu recovery CD for restoring lost/damaged
grub.

*Suggested solution*: I wish for benefit of newbie/users like me, the
following suggestions are made below for consideration.
Create one General Recovery CD for all ubuntu versions - to restore/recover
the lost grub as well as all OS if any. due to unforeseen circumstances.

OR if Recovery Mode/option added to the Grub in the installed ubuntu -
it should be able to restore the damaged/lost grub to original position
automatically.
For this purpose it should be introduced in all existing ubuntu and future
one. This option will encouraged the newbies/users like me to use ubuntu
without any fear/frustration and thus preven runaway from ubuntu.

The position may kindly be brought to the kind notice of appropriate
authority
/team - for consideration and implementation.
With warmest regards,
-sriranga(79yrs)
