MBR backup:

dd if=/dev/hda of=mbr_backup.bin bs=1 count=512

Swap if/of around to recover the entire MBR .

The partition table is located in MBR at 0x01BE (446) offset and consists of 4 records of 16 bytes.

To recover the partition table only:

dd if=mbr_backup.bin of=/dev/you-device bs=1 count=64 skip=446 seek=446

    I do not know whether it's just me or if everyone else
    experiencing issues with your site. It appears like some of the text within your content are running off the screen. Can somebody else please provide feedback and let me know if this is happening to them as well?
    This may be a issue with my browser because I've had this happen before.
    Appreciate it

    Hi are using Wordpress for your blog platform? I'm new to
    the blog world but I'm trying to get started and set up my own. Do you require any coding knowledge to make your own blog?
    Any help would be greatly appreciated!

    Howdy, I do believe your web site could be having internet browser compatibility problems.
    Whenever I take a look at your web site in Safari, it looks fine however, if opening in IE, it has
    some overlapping issues. I merely wanted to provide
    you with a quick heads up! Other than that, fantastic website!
