Cannot boot from Yumi multiboot USB stick
I've just created a multiboot USB stick using Yumi. I tried to start my notebook (Asus K70IO) using it, but all I see is just a black screen with blinking underscore even after waiting for minutes. If during this time I remove the USB stick I get the message: "Operating system load error".
How do I properly load my Yumi USB stick and use it? I've tried formatting it using Yumi's checkbox to format the stick in FAT32 too, but it didn't help.
Now I tried to use Sardu 2.0.5 and met same problem: black screen and blinkin underscore, if I remove stick I see "Operating system load error" and my OS starts to boot.
At the same time if I create bootable USB stick from ISO using UltraISO it boots smoothly.
Solution 1:
I know its a couple years late, but here goes....
It can be a factor of factory formatting. Many USB sticks are formatted USB-FDD (Floppy disk) when what you really need is USB-HDD. Windows inherently formats USB drives as FDD for which it will not write to MBR. But with a specific command line called DISKPART you can wipe the disk and set it up as a USB-HDD with an appropriate MBR. Here are some pretty simple steps, take caution though, one small misstep could send to "no-reboot land":
- Run Comand Prompt as Admin and use the following commands:
- DISKPART
- LIST DISK - find the disk number of the usb drive
- SELECT DISK # - # being your usb drive ( WARNING MAKE SURE YOU ARE SELECTING THE CORRECT DRIVE OTHERWISE THIS COULD BE DISASTROUS )
- CLEAN
- ACTIVE - Make the drive active
- FORMAT FS=FAT32 - fat16/32 are the best option for syslinux
- ASSIGN
- EXIT
This should get you ready to go unless the USB drive is truly the culprit. This just fixed the exact SAME problem I was having with YUMI.
Solution 2:
So the problem is solved. Seems that something was wrong with 2 USB sticks(Kingston DT 100 G2 and Spaceloop XL), because when I made bootable USB with third stick - it started without any problems. But still, I can't understand why these sticks weren't working.
