Help: Burned ISO CD Doesn't Boot.
 

I downloaded and burned the ISO of the Vector Linux 4.0 Live CD. Checked

the md5sum. However, after burning, the CD does not even boot.

I used another Mandrake CD to boot, my PC booted with that CD no problems at all. This verification indicates that there is probably something wrong with the burn process or the CD.

Here is the CD Burn Log:

I also have the Vector Linux 3.2 CD. I tried to make a duplicate of it using xcdroast. The duplicate doesn't boot either. Please assist.

Thanks.

to dest if the burn went well. do an md5sum on the raw cd-rom drive.

md5sum /dev/cdrom

see how that comprares to the md5sum on the iso. (you may need to be root, and this seems to only work on some distro's)

Did that here are the results:

bash-2.05b# md5sum /dev/cdrom
md5sum: /dev/cdrom: Input/output error
bash-2.05b# md5sum /dev/cdwriter
md5sum: /dev/cdwriter: Input/output error

I am unable to mount my CDROM and read data files. Had started a separate thread in this regard some time ago here. Still this issue exists. In the past, I was able to burn CDs successfully, however now even this doesn't seem to work. Hence, I feel that I should also learn Kernel changing etc., to get more familiar with some of the intricacies.

burn as "from CD image"
 

You guys probably no more about this than me, but perhaps you need to specify that you are burning a CD which is meant to be bootable (as opposed to raw data). In the output you posted, there is a line which has "-data".

I know that with something like Roxio, I needed to specify that the CD was to be burned from a CD image using the graphical menus....something like file -> burn from CD image -> select location -> select .iso format. If I didn't, the data would be there, but would not be bootable.

Did you ever try burning bootable CD's before. I saw that you were able to burn before, but perhaps you were just burning raw, unbootable data.

Burning bootable CDs has worked very smoothly before. Never had this problem. Also, only when duplicating it said Data CD. I went to the create a CD menu and followed all the options there for writing a CD. Done this several times before. It wouldn't work either.
