Hi good fellas!i've been experiencing some hard times and need a piece of advice.
i'm a dual boot user on 2 hdd linux on the first one and windows on the second

let me start from the beginning

i had recently fedora 10 running on my machine (after trying debian etch). i believe it all works fine a part from some graphical problem on fedora.with the company i job in using ubuntu for our linux box , i wanted to dig a bit more in linux (i originally used linux for fun)

1st problem
After booting the ubuntu 9.04 i ran into busybox shell with initramfs promt. i google it and found it was a bug so i dowloaded a fresh one.its the same thing

2nd problem
I had and old ubuntu 6.06 that i could install seamlessly.i upgraded to 8.04 and then to 8.10 and after rebooting my mouse and keyboard have stop working.I enable in the bios the support for usb legacy keyboard.that didn't solve my problem when i boot with the 2 previous kernels.but with the new one i had error like: "acpid can't open socket /var/run/acpid/" and plenty stuffs like the other time.just that i didn't have time to copy everything and it switches to command line code.all the time i repeated the process but it doesn't happen again and all i have is command line login.

3rd problem
i wanted to go back to fedora and this time i download the version 11. and now i'm having Buffer I/O error on device sr0, logical block 5 and it repeated with different block number.the suprising part is that it's now the same with the fedora 10 i installed before.


So with google help i found it might be either my dvd, my dvd drive or maybe my ram.I tried both the ubuntu 9.04 and the fedora 11 on different machine and they all work. so i assume it was my dvd drive.But the ubuntu 6.06 livecd still works fine.at this point i'm confused.

So for me it was maybe the speed i burn the iso.usually i use alcohol 120% to burn the iso using the wisard and at maximum speed.So i've wasted 2 cd already trying to burn at a different speed than the maximum.

my last chance is to mount the image to a virtual drive and copy it's content and burn a new copy using a lower speed but i'm a bit worried about it stop being bootable.It that ok about this plan? please help me out and thanks for reading this

Using your Ubuntu LiveCD, run Memtest to verify the integrity of your RAM. It's in the main menu on the CD. If your RAM is OK, check the MD5 checksum on the ISO you wish to burn. If that's OK, burn the image at a SLOW speed (8x or slower is best).

No... It would not be bootable.

Hope this helps.
