Dual Boot installation problem

Asked by Ben Flanagan

Hi,

I have been trying to install ubuntu 10.10 alongside windows 7 for the last 10 hours. I created a live CD and was using the ubuntu partitioner inside the CD.

The installation process gets up to about 50% and then gives me a " errno 5 input/output error ".

Ive tried google and carried out some of the reccomendations that I have found but none have worked.

Ive checked the iso, i moved my computer to a cooler environment and i created 4 different live cd's at the reccomended write speed of 1x. I have also tried the USB installer. None of these have worked.

From what i have read this problem has been around for quite a while.

Does anyone have a definite fix or know what I am doing wrong. Is there another way to install. I know how to manually create partitions using windows disk manager and I have backed up my files and made a recovery disc.

The iso I have is ubuntu 10.10 desktop i380.

My laptop is a HP-G61, with 3GB of RAM, dual core processor, 320GB HD, 64-bit.

Will the 10.10 amd64 iso be better.

Please help.

Have you tried the alternative installer disc? Did Ubuntu 10.04 work on this machine?

Looks like an error of reading CD.
You could clean the len of CD drive. Hardware issues also exists.
Else you can install from a USB key, to see if you get same error.

Hi,

Im just downloading the 10.04 iso now. Ill try that.

Ive already tried the USB installer and I get the same error. Ive tried writing at the slowest speeds possible to a CD-R and to a DVD-R but still get the same error.

If I click "try ubuntu" it works fine. I cleaned my lens, also and it made no difference.

If i try the installer disc and install onto a partition I make how will I be able to select which operating system to use on boot up with no grub.

You can't, or you will have to install another bootloader (one of Windows, Lilo, Supergrub, ...).
In fact, I don't understand clearly your last phrase.
" errno 5 input/output error " is usually due to a defective CD or hard drive.
As CD and USB stick can't both be defective and MD5 is OK, it could be hard drive. The writing fails at same block, giving same percentage. At partition step, could make a empty partition (e.g. 30GB) at start of disk, to shift start of other partitions and see if it reduce the percentage reported during install.

My last phrase just means that with the ubuntu installer it automatically creates a partition and installs ubuntu onto the partition alongside windows. On system start up I can select which OS I want to use. If I manually create a partition with windows disc manager and manually install ubuntu onto that partition how will I select which OS to use on system start up. You answered it though.

Every time my installation fails on windows start up it carries out a CHKDSK and reports back no errors. Ive also checked my RAM and no errors were found. I use windows disc manager to remove the partitions that the ubuntu installer created and carry out full diagnostics and every thing comes back fine.

Both the live CD and USB fail with the same error and it occurs at a different percentage every time. I checked the iso with WinMD5.

My Ubuntu 10.04 iso has ten minutes left of download time and ill try that and see what happens.

Im sorry, I rechecked the MD5 and it did not match this time. How can I fix this. Do I just download the 10.10 iso again.

Yes, you will have to download again.
Else you can use a torrent, as MD5 check is included in P2P software.
