First, create a CD of the Recovery Partition, if you have not done so. You then have no issues with losing that partition. Now, for the main item: Whether you should upgrade to business depends on what you are doing now, but the main problem is getting devices to work for want of Vista drivers. If you can get around that, then upgrade if you really have need for the new or extra features of the business edition. Also note that for some applications/programs, you may need patches for them to work in Vista.
I would clean-install to avoid the problem of not being able to activate the original OS (XP ?), which you will be able to by using the Recovery disc, but if you upgrade, you change the status of the origional OS to Vista Business - there is no going back. However, if you clean install(full retail or OEM pack), you still have the origional OS.
I have a Dell Inspiron 6000 with the following specs
Pentium M 1.6 Ghz
1.5 GB RAM
128MB dedicated graphics ATI Radeon X300 (with pixel shader 2.0)
120GB Hard Disk
Now I have the following questions about upgrading to window vista business.
1. Should I install or not?
2. Will I lose the Dell Recovery Partition if I do install? and if I do, is there any way to make a new recovery partition?
3. I read in various places that there are compatibility issues regarding sound card, wireless card and a few other things with my model of laptop? Is this true and to what extent?
4. Clean install or upgrade? People have told me that upgrade slows the system down, is this true?
These are all the questions I have for now and a few answers will be appreciated. Thanks
