I am a beginner and want to try Ubuntu for the first time.
I have the Lenovo Y700 laptop with UEFI (access to UEFI with "NOVO" button)
I want to install Ubuntu on my external HD (WD My Passport 1TB), without influencing the system boot, UEFI and the internal drive (with Win10 on it).
Now, I know that many users had problem after installing Ubuntu on an external HD on a PC with pre-installed windows in EFI mode.
As I understand, to prevent changes in the UEFI, one of the solutions is to install Ubuntu in Legancy mode. I don't mind to change between Legancy mode and the UEFI anytime i need to use either Win10 or Ubuntu.
So, i used Rufus with the image ubuntu-16.10-desktop-amd64.iso to make a bootable Ubuntu installation USB Stick first. I set it for MBR partition scheme for BIOS or UEFI in FAT32 file system.
Then I boot Ubuntu in Legancy mode, connected to the network and start the installation progress.
- I've chosen the boot loader to be installed in dev/sdd (my dedicated external drive).
- I created two partitions on my sdd drive: swap partition and main ext4 partition. there is another big NTFS partition that i don't want to use for Ubuntu.
When i press Install Now, instead the regular "write the changes to disks?" window to confirm the changes and start the installation, i get the following window:
go back to the menu and correct this problem?
The partition table format in use on your disks normally requires you to create a separate partition for boot loader code. This partition should be marked for use as “Reserved BIOS boot area” and should be at least 1 MB in size. Note that this is not the same as a partition mounted on /boot. If you do not go back to the partitioning menu and correct this error, bootloader installation may fail later, although it may still be possible to install the boot loader to a partition.
there are two options:
- Go Back - to create the "Reserved BIOS boot area" partition.
Which of these i need to choose, in order to not make any changes to my internal drive, to the UEFI settings and to not harm the WIN10 boot?
