The boot selection failed because a required device is inaccessible

[aab001]

Hi,


After installing ubuntu 13.04 I couldn’t boot any operating system and I got the message "The boot selection failed because a required device is inaccessible"

then I used the boot repair disk and I got the grub menu and i can boot the ubuntu but I cannot boot the windows and I have the same message when I tried to boot the windows."The boot selection failed because a required device is inaccessible"
The bootInfo URL is paste.ubuntu.com/5764282


many thanks in advance

Ah i am sorry to be the bearer of bad news but it appears you've deleted your windows partition.

no it is there

I'm not sure what is a good website to explain how windows OS uses partitions, but essentially it requires 2 partitions to boot up, one of which is missing (the main one).

if you look at your fdisk output.



Device Boot Start End Blocks Id System
/dev/sda1 * 2048 1023999 510976 7 HPFS/NTFS/exFAT

Start: 2048
End: 1023999
Blocks: 510976

each block is 1024 bytes, this means sda1 has a size of ~500 Mb which cant possibly be your windows partition.
Compare this to your swap partition (sda5) which has a block size of 4881408 (or approx. 5 Gb).

Looks like you have lost your actual windows install

sda1 is just the windows boot partition, given it's size anyway....

I posted again because I believed that I have posted in the wrong section, also your first answer shows that you are not confident with it (Ah i am sorry to be the bearer of bad news but it appears you've deleted your windows partition) and you didn't give a solution. In fact, I am really in a bad situation so I tried to find any one who can fix this problem.
Sorry for any convenient I may did
cheers

OK, so it's a sad situation.
If you don't have a windows DVD, you might try and borrow one. Else buy one.
Or just live without windows
