Need to know what hard drive sector Trisquel starts the install

As the SSD hard drives need to have the operating system start on an even number sector of the hard drive (preferably 1024 or 2048) - I would like to know the sector number a new install would start with in Trisquel.

Thank you,

Cal

I don't know what the default is but it really doesn't matter.

Probably the easiest way is to partition manually. If the installer isn't smart enough for the job, use http://gparted.org/livecd.php (GNU GPL 2+)

Cal,

why on Earth would one need such informations ?
In general every operating system writes the MBR (master boot record) to the first 512 Byte of a harddisk. Then the rest (boot partition, boot manager) follows.

For reference:

There is an embedding space for the bootloader after MBR and before the first partition. The issue is where the partition starts, DOS prefers a start not aligned to 4096 bytes. Manual partitioning certainly works for it, I don't know what default is there now.

Thank you for the info Michal. Is there a way, (as in Windows using diskpart in a Windows command box) in Trisquel to find what the starting sector on the hard drive is - if not, then by partitioning manually is the only certain way?

Regards to all who've responded -

sudo fdisk -l -u=sectors

Thank you very much Lembas! That is what I needed! :\

I'm getting that the -1 is not recognized

Ahh - my mistake that is a l for list, correct? I was inserting wrong.

That's why: http://www.rodsbooks.com/gdisk/advice.html#alignment

Also, I always recommend people to use GPT instead of (common) MBR, because of more flexibility (you can get rid of logical/extended partitions!) and reliability (CRC32 embed... or sth. like that). See: http://www.rodsbooks.com/gdisk/whatsgpt.html .
