Superb explanation. Thank you for that.<br><br>I never knew the leap from the BIOS to the hdd.<br><br>Lets take this scenario.<br><br>First I have only one which is 40gb in size. I install OS say Ubuntu on it and I realize that after the entire install and upgrade the installed size is only 6 gb I dont want to waste the space, so I resize the drive to have 10 gb and release the other 30gb for something else.<br>
<br>I then reboot, all are happy.<br><br>Then I decide to buy a 20gb drive. I then put that as the SATA2. I then use GPARTED to copy Parition 1 from Physical Drive 1 (the 10gb one) to the Physical Drive 2. All is well so far.<br>
<br>I unmark the 10gb paritions as NON-BOOTABLE and the 20GB one as BOOTABLE.<br><br>I shutdown then unplug the Physical Drive 1 out of the machine. I restart the computer.<br><br>Now I am hosed. I have not idea but the machine does not come back.<br>
<br>Does GPARTED not copy the MBR and other data to the Physical Drive2 from PhysicalDrive1, 10gb partition ?<br><br>I always though that it replicates bit by bit from disk1 to disk2.<br><br>Kindly correct me/ educate me here on where I missed and what I missed.<br>
<br>Thank You<br><br>-Narahari<br><br><div class="gmail_quote">On Mon, Mar 21, 2011 at 12:45 PM, Michael Trausch <span dir="ltr"><<a href="mailto:mike@trausch.us">mike@trausch.us</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
Perhaps a little bit about the boot process of a typical x86 family<br>
system would be in order here.<br>
<br>
When an x86-based computer boots up, it's BIOS runs through a series<br>
of tests to ensure that things like the processor and memory is<br>
working. It then attempts to boot up; it does this by looking through<br>
all boot devices in order, reading the first sector on the drive. If<br>
it ends in the bytes 0x55 / 0xAA (or maybe the other way around, I<br>
can't remember), then it loads the sector into memory and jumps to it.<br>
That sector is responsible for the first stage of the boot process.<br>
In the case of a hard disk drive, the first sector is actually the<br>
master boot record, which will then find the active partition and boot<br>
from it, if it has a standard program. Of course, any program can be<br>
installed in the MBR or boot sector of a volume, and so as is usually<br>
the case in places where software is involved... well, anything can<br>
go. :-)<br>
