    BIOS to allow booting from an ISO on an HDD.

    Hi there
    I'd like a feature in a Bios to enable an ISO on the HDD to be a selectable boot device.

    Some MB's have a small Internet Browser built in to the BIOS which can be activated at boot time before loading the OS.

    Perhaps even if loading a file system into the BIOS wasn't possible perhaps by selecting this type of option in the BIOS Windows could issue a prompt for the ISO once it could read the file system before loading the rest of its code.

    Shouldn't IMO be impossible to do and would certainly make life a lot simpler.

    Problem is when the BIOS goes to the HDD, first stop is the MBR. How is it going to find the .iso from there. Maybe if you put it into an active partition all by itself. But now it is looking for a bootmgr there. I guess one would need a "look for .iso" option in the MBR.

    Well Jimbo,

    true would maybe be easier, but would it be any faster. I use Iso2disk to convert the Iso right on a USB stick or drive and this takes a while.

    But i think that installing from ISO, this would take a lot longer to end.

    I think he meant burning an iso to a disk.
    Could be this one:ISODisk, free software for mount and create ISO disk image

    I can't find Iso2disk program. Instead, there is a free program called ISO2Disc.

    That looks like a good program, it would solve some problems for me.

    I think I see what Jimbo is saying, he'd like to boot to any ISO image that's stored on the hard drive. That would be difficult to set up. The BIOS would have to first mount the hard drives, then search a predefined area on it and mount any predefined ISO image which may be stored there, and boot to it.

    I don't think any Motherboard maker has even thought of doing, but it would be great if it could be implemented.

    Jimbo's post is several years old but it has been revived. I don't know of any BIOSs that support booting from an ISO on an hdd but look into the Zalman ZM-VE300, ::: Zalman, leading the world of Quiet Computing Solutions :::. At first glance it appears to be an ordinary external hdd enclosure but it has a feature that makes it very unique, it can emulate a CD drive. The enclosure can do exactly what jimbo was asking for, I have one of the Zalman enclosures and have dozens of install ISOs stored on mine. It allows me to select one of the ISOs on the hdd and then boot from it just like it was a disk in a CD drive. It works great and now I have a single place to store all of my install disks as ISOs and don't need to sort through stacks of disks to find the install disk I'm looking for.

    That is one remarkable HDD! Are they within poverty level buyer's range? That would save me all kinds of problems, I could cart that around with me for on-site jobs, instead of taking my huge CD wallets with me.
