Most people I see, use dual boot operating system is there Desktop PC (off course with win98se & winXP). I asked them & my self what are the (+) & (-) point of having a dual boot operating system? I came up with following answers. Off course they are my own views, thatâ€™s why I am putting this comment on the forum. So I am expecting you to post your comment on this. I donâ€™t know whether it has already been discussed on this forum. I am expecting you to post your comment on this. 1. (+) Protection from virus. Lot of user use windows XP & NAV or AVG as main OS & AVS to work on internet. They say in case of major virus attack they can boot into the second OS & download update or the patch or use the second avs to scan & cline. (-) though some of them agreed that if a good avs & OS like winXP can be keep updated they can escape a major attack. & off course Linux OS are very safe. 2. (+) recovery from a crash. Another advantage of dual boot operating system is easy data recovery. In case one OS crashes second OS can be use to recover data very easily. This option really helps the amateur users as they can obtain there data or can keep working. (-) you really donâ€™t need a dual boot operating system for it as windows XP has great options like system restore to prevent & recover your system from a crash. If you maintain your system properly like updating your OS & a good AVS regularly & staying away from the system files you can prevent a crash. If I am not mistaken Linux OS donâ€™t crash often. But again this option may be for an advance user. 3. (-) almost every one agreed that dual boot operating system does slows down the PC a bit. (+) but PCs going faster & faster every day that point can be out of question. 4. (-) there is a license issue. (+) but for discursion of use we will keep that point out. As I said earlier this point were raised by my friends & me. I am confused, whether one should go for dual boot or not. So I am answas to see much more comment on this.
