I think that's specific to an OS. Otherwise how cacn you create two extended partitions in linux? > is hda4, the data would be written to hda5 (the default logical) > If you make hda6 to hdaN, the boot record would still be of hda4 What's a boot record? A sector of 512 bytes at start of a partition. What's a partition? Range of sector/cylinders indicated in MBR at specific location in specific format. What's an extended partition? A partition which has partitions inside it. The information in that is stored in boot record of extended partition... What's MBR? It's absolute zero sector of HDD. What's a sector? A number you can read by issuing some command HDD controller. Frankly all this extended/logical/primary stuff matters to BIOS and OS. Until linux arrived, we had flaky BIOS and some shabby OS. Now we have limited capacity BIOS and thankfully a real OS. In the nutshell, even /dev/hda5 has it's own boot record. Of course correct me if I am wrong. But I have installed lilo on extended partition, made it active and boot windows from there.... Feels good recalling all this stuff... and nostalgic too..Something like 'Give me 30 ruppes to fix your autoexec.bat' or 'Solder this circuit for me and I will repair your hard drive with norton utilities'..;-) Shridhar _______________________________________________ linux-india-help mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/linux-india-help
