[opensuse] make bootable an otherwise unbootable device
Hello, This is not a new problem, but it proves habing unpleasant side effects. My ASUS N550JK laptop have initially a dvd reader/writer I have now little use of. So I replaced it by a caddy and drop in there a 500 Gb ssd. My problem is that if dvd are perfectly bootable, the ssd in the caddy is not. is there anyway to make this device bootable? thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

It is up to your BIOS, there is nothing that can be done from OS side if BIOS does not allow selection of this device as boot medium. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

to allow booting, it needs to see it as a dvd, probably a trick like the one for booting isos on usb pen (but the other way round?) if time permits, I could try to write a dvd iso to the disk mbr? jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

DVD and HDD are two different types of ATA devices. It is most likely not enough to write ISO onto HDD because BIOS will never even attempt to access it as DVD. Otherwise nobody needed hybrid images in the first place.

Which just proves what I said.

I doubt any ISO image could fit into 512 bytes, given that ISO block size is 2KB. If you mean overwrite whole disk, it would be interesting to know whether it worked. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

of course. I know it's possible (because I own an iodd https://www.amazon.fr/gp/product/B00S3G12E6/ref=ppx_od_dt_b_asin_title_s00 device that do just that: make a hard drive be seen as a dvd. but I don't know how and don't know is this can be done at os level how do syslinux works? surely documented somewhere thanks jdd -- http://dodin.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
