I want to use rufus to setup multiboot , my case is below

I have a windows 10 , and downloaded ubuntu server

I setup rufus and created boot disk to USB drive , when boot from the USB , it pops "Block probing did not discover any disks. Unfortunately this means that installation will not be possible"

I am wonder if the USB do not mount the hard drive when boot .

any advise to fix it .

Thanks

Do you have another computer you can use to try to boot the USB?

The most likely scenarios with windows 10 installed is that you have hibernation on (the default with windows 10). Check your power setting in windows 10 and make sure it is off. Your Ubuntu installer would not mount a hibernated partition because of the high potential for data loss. For future use if dual-booting, some windows updates will turn it back on and the user will not be informed.

Rufus wasn’t designed for multiboot

I think what the original poster meant is that he wants to use rufus to boot the ubuntu server installer, which he plans to install dual boot with windows. So no need for rufus to multiboot anything. The other reply is likely right, the OP needs to shut down windows completely for the ubuntu installer to be able to do anything with the drive.

For usb or hard disk?

This wouldn't be the first time I misread a post.

Rufus has the option to select dd image mode after pressing start, The dd image mode sometimes will allow the usb to boot if the default mode won't. The downside of the dd image mode is the filesystem is iso and will be read-only.

thanks reply ,

work for one PC , but not work for another PC

What other PC? Your original post only mentions a specific PC with a particular problem booting. You need to post more detailed information on this additional PC and what the problem situation is. What boot options did you have and select, what OS (if any is installed) and exactly what happened when you tried to boot.

I have a few PC want to do that , after disable hibernation on windows 10 , some PC can detect disk , however , some PC still shows not detect disk , the disk type is GPT .

I use rufus to setup ubuntu .

What you mean boot option ?

Do all these other machines also have windows 10 installed? Some other Linux OS or some other version of windows? Are they all UEFI? If they have windows 10 and are GPT then they would be UEFI.

Do you get any messages or do you just see the installation type window without partitions on the drive showing. I've not used the server edition and am not familiar with it.

Boot options in the BIOS to select the USB installer with the Ubuntu server iso on it. Do you have options to boot the USB in UEFI mode as well as Legacy mode and if so, which do you select.

Is this the usb or computer drives?

One thing I have noted with certain windows systems & hardware.

If the drive (particularly on laptops) is configured in raid mode some installers cannot even see the drive. In most of those cases I have seen the fix is to go into the bios and switch the sata system from RAID to AHCI. That then requires a repair of the windows system to allow it to boot again.

After the above fix the installer then can see the drive and will install to it.

Don't know if the OP has this particular case or not, but it is a possibility.
