Hello,

Thank you for taking the time to report this issue, but it seems that it needs more information in order to be looked at.
It would be useful to provide more information on the steps you followed and run into this issue so it can be reproduced.
If you mounted the partition where you chose to install Ubuntu GNOME *before* you proceed to the installation, then it is not a bug, because a partition should be unmounted when the installer makes changes to it.

Best regards,
Elias

Hello..
I'm installing ubuntu using USB flash.. the dialog said it need to unmount /dev/sdb while i want to install to /dev/sda

workaround: when i click back then continue again, the Continue button is now enabled in *Installation Type* . and i can continue installing

I think I had a similar issue, "continue" button was grayed out in the installer on the "installation type" screen. The steps I used were:
* Boot from USB drive with 15.10 beta 2
* Click through the install, get to installation type (erase full disk / install alongside question). No popups / unusual questions so far.
* "Continue" button is disabled regardless of option chosen

Going back in the wizard, then forward again, let me continue further. This was on a machine with an existing Windows install, if that matters

Same problem here, trying to install lubuntu 17.04 in my old Aspire One and that problem happen anoynly every time. Reading about the problem i found a question about the ACPI, so a decide to turn it off, but Lubuntu doents have the menu options to choose the grup parameters, then to change the boot options of the lubuntu you have to edit the file \boot\grub\loopback.cfg on the pendrive, and add the parameter "acpi=off", near the "boot=casper" i think its a good place.

this is my entry that works
menuentry "Install Lubuntu" {
 linux /casper/vmlinuz file=/cdrom/preseed/lubuntu.seed cdrom-detect/try-usb=true noprompt floppy.allowed_drive_mask=0 acpi=off ignore_uuid boot=casper only-ubiquity iso-scan/filename=${iso_path} quiet splash ---
 initrd /casper/initrd.lz
}

and with that option the installer can go on
