Доброго всем дня! Вообщем купил флешку на 256GB и сделал её мультизагрузочной (ф/c NTFS, загрузчик Grub4Dos). Сперва всё получилось, но потом почему то стало выдавать ошибку. Есть ощущение что ему не нравится файловая система NTFS...
The disk contains an unclean file system (0,0)
Metadata kept in Windows cache, refused to mount.
Failed to mount '/dev/sdb1':Operation not permitted
The NTFS partition is in an safe state. Please resume and shutdown
Windows fully (no hibernation or fast restarting), or mount the volume
read-only with the 'ro' mount option.
mount: mounting /dev/sdb1 on /isodevice failed: No such device
Warning: Cannot mount /dev/sdb1 on /isodevice
Could not find the ISO /ubuntu-16.04-desktop-amd64.iso
This could also happen if the file system is not clean because of an operating
system crash, an interrupted boot process, an improper shutdown, or unplugging
of a removable device without first unmounting or ejecting it. To fix this,
simply reboot into Windows, let it fully start, log in, run 'chkdsk /r', then
gracefully shut down and reboot back into Windows. After this you should be
able to reboot again and resume the installation.
