I am trying to install Ubuntu mate for first time alongside with Windows 8. I have two hard drives.
Windows 8 on one hard drive and now trying to install Ubunt Mate on second Hard Drive. I am getting the following error message when I finish partitioning and press install now button:
“The partition /dev/sdb1 assigned to / starts at an offset of 3072 bytes from the minimum alignment for this disk, which may lead to very poor performance.”
I have also search on Internet for its resolution but all in vain. Can anyone help me in it ?
Thanking you.
This kindof sounds like the first partition on the second drive does not start at a multiple of 4096 bytes. A bit odd that you get the message for the first partition - usually that problem tends to happen on the second/third/etc. if you choose the sizing of the preceding partition in a way that does not align to the blocksize.
Does this happen with automatic or manual partitioning?
Edit: maybe post the entire partition layout for the second disc, if possible.
I am attaching the error message which i got along with partition layout of both drives. Can you please suggest me its resolution. Waiting for your prompt response.
I really don’t see why this error would happen that partition.
The boot loader device looks potentially wrong, though - usually it goes directly on /dev/sdb and not one of the partitions. Then you use the boot menu / boot order selection of the BIOS to select which drive to boot from.
I don’t think the bootloader selection has any influence on the partitioning, though, but try it with /dev/sdb anyway.
If that does not change anything maybe try a different partition layout.
Dear Can you suggest me any partition layout. I have tried couple of layouts but got same error message. Please help me in its resolution so that I can Install Ubuntu Mate.
Maybe it helps wiping the start of the second harddisk (assuming it is /dev/sdb, this command should do it: sudo dd if=/dev/zero of=/dev/sdb bs=4096 count=1000).
Big, fat warning: make 100% sure you aren’t accidentally wiping your other disk if you pick the wrong device name! First check with lsblk which lists all discs and their partitions.
