Three Is The Magic Number

My HowTo on is by far my most popular post, pulling in new visitors everyday. The only reason I wrote it is because it was something that happened to me now and again. But what about dual boots?

What happens when your NTFS drive goes beserk, and you only have access to your Ubuntu install? Well, finally, I’ve come across a solution. Now, before we begin, this HowTo assumes that your Ubuntu install is working as normal, and that the NTFS partition isn’t essential to Ubuntu. It’s also possible (though I’ve not yet tried) to follow this HowTo using First, we need to find out what partition we are dealing with. To do this, open a terminal and type; sudo fdisk -l That’ll give you something like this; Disk /dev/sdb: 160.0 GB, 96 bytes 255 heads, 63 sectors/track, 19457 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x2709a320 Device Boot Start End Blocks Id System /dev/sdb1 * 1 88321 7 HPFS/NTFS /dev/sd1 is in this case the NTFS drive we’ll be working with. Obviously change this to whatever yours is. If your partition isn’t listed here, or appears to be the wrong size, you’ll need to use.
