You are taking this way out of context and way off topic.
You said he could use ANY disk for his install. I pointed out that is not true. He has to use an OEM specific disk.
However, any Windows 7 Home Premium disk should work for re-installing your OS -- your license key should already be on your machine
This is the statement that i am saying is incorrect. As that statement is not true at all. You cant use any disk, you must use an OEM specific disk.
He doesnt have a Dell so all your talk about Dell disks is serving no purpose. Yes your right if he had a Dell and borrowed a Dell OEM disk he could just install. But he has an HP so that is completely irrevelant to the topic at hand. It wont generate a key for him that will activate. It is a completely different manufacturer and it doesnt help.
I have experienced plenty of issues using a disk from one OEM on another OEM machine. It can and does happen. Be glad that you havent had that happen to you.
Where did i say that Dell Software is anything to do with Windows? No where. I said that the OEM disks are tailored. Meaning that a Dell Disk will include things like the Dell Support links, which he wont need being on a HP machine. That is what i mean by being tailored to the system. You competely misunderstood what was meant by my comments.
I still dont understand why your pushing this Dell arguement. Cause simply put, he is not using a Dell so what does it matter? My point was simple. Use OEM with OEM and Retail with Retail. I dont know or understand why your arguing when all i did was point out that your statement saying he could use any disk was incorrect.
You havent come across any issues using an OEM disk on any machine, well congrats. I have and it isnt pretty to try and fix. Considering that no machine now comes with media at all unless you order it and pay extra, this whole arguement is kinda silly. All machines come with Recovery Partitions that you either can boot to or burn your own personal media from. So he would have to order the media from HP and the whole arguement is null and void cause he is getting it directly from the OEM anyways. Which negates this whole arguement.
My point was simple. I was just showing how you cant just use any disk. As there is a difference. Not everyone knows or understands that and i was just trying to make it known and understood that the use of just any disk would be trouble.
