Iso Injecting

[HalStyli]

Hello,

I have a few ISOs, mostly bootable but not all and I would like to update them with a file or a whole folder - and maintain the bootability if it was there originally.

I get the impression you have to extract everything to a folder, update the folder, then create a new iso with the extracted boot image. Presumably there is no (free?) tool where you can simply drag and drop straight into an ISO image?

Assuming not...

a) Can someone please recommend a tool for doing this as simply as possible on XP.

I have been experimenting with cdimage and wondered if there were other favoured methods?

B) What about Linux?

I have used Mkiofs / cdrecord in the past. Are there better ways (preferably free)?

Thanks in advance for any help given.

Hal.

You can modify/update ISO files with UltraISO and you keep the bootable feature ... but the demo limit to 100mb file
