Booting from USB iso image
 

I am attempting to install Oracle VM Server from USB. I get the loader/installer to run, but when it is ready to install the iso, it asks 'What type of media contains the packages to be installed?' I reply 'Hard Drive' then it takes me to a list of devices (/dev/sd*) which are not mapped to my USB as far as I can tell. It doesn't seem to be able to find the USB drive that it originally booted from. I don't see any way to configure or point to the USB drive. Any assistance is appreciated.

I created this bootable USB using YUMI-0.0.7.4.exe to boot from memory.

Thanks,

Mike

I think we need a bit more information.

What is the host OS?

Do you mean to say that you have booted to a usb flash drive of some linux OS that was made from a live cd?

The host OS is what I am attempting to install from USB. Oracle VM Server is Oracle's version of VMWare. I have an ISO image that I downloaded from Oracle technet. I have attempted older known-working versions of Oracle VM Server, but get the same result.
I get the installer to run and select language and keyboard, but the 3rd screen asks for a media location of the packages to be installed. The list presented is:
Local CDROM
Hard Drive
NFS image
FTP
HTTP

I choose Hard Drive (as my USB is booted as a HDD) and am presented with a list of devices, /dev/sd* of which none contain my media. I don't know how or if the USB is mapped to a device so I don't know how it would be accessed by the installer. This may be a due to the fact that it just can't find the package location on the USB. Doing some more research on my end, but appreciate any assistance.

Thanks

Did you try selecting Local CD ROM also? It may well not work but it's worth a try at least.
If not then you may need to get out of the installer and mount the USB drive somewhere then re-run the installer. I have never seen the OS you're trying to install though so I wouldn't know how to accomplish this.

Live usb creator are funny things. They might let you boot to a hard drive choice but the thing may still think it is on cdrom.

If you can get to a terminal you can run mount command to see what is mounted.

I believe the problem is related to isolinux. Still digging into it.

Starting in version 3.72, ISOLINUX supports a "hybrid mode" which can
be booted from either CD-ROM or from a device which BIOS considers a
hard disk or ZIP disk, e.g. a USB key or similar.

To enable this mode, the .iso image should be postprocessed with the
"isohybrid" script from the utils directory:

isohybrid filename.iso

Thanks

I'd dd the file image to a usb if it is indeed a hybrid iso.

To boot directly to some iso images, you can use the tips at www.pendrivelinux.com for grub4dos or even grub.

Why are you doing this with YUMI? I don't see any RedHat distro's on the list of supported ISO's.
