Unfortunately, you just admitted to using pirated software, so the rules of this forum prohibit anyone from helping you. Whether you know it or not, what your friend is doing is NOT legal, and could get him into quite a bit of trouble. I would strongly suggest advising him to rethink this sort of thing in the future.
Best thing I can suggest is that you contact HP and see if they would be willing to supply you with a set of 32-bit install media. If not, then you'll have to decide what you want to do.
Also, it should be known that if your new system came with 4GB or more of RAM, which seems very likely if it's shipping with a 64-bit OS, you will lose access to that RAM by using a 32-bit OS. A 32-bit Windows will only be able to use about 3.25GB of RAM, and this will not change.
I recently recieved HP dv5-1119nr as a gift for Christmas. It has a Windows Vista Home Premium 64-Bit OS. I am a DJ and Use Numarks Virtual Vinyl audio Interface which is for my turntables. I have no complaints with the notebook. Unfortunately, the interface is not compatible with 64-Bit, and according to Numark may not be anytime soon. I had a friend upload his Vista 32-Bit OS for me to download, as a matter of fact he sent me two to choose from. I have (frustratingly) tried multple times to burn and re-install a 32-Bit system. I have tried using Cyberlink DVD Suite to save the .iso file (I understand that). It shows up looking like a winrar file, but in properties it does say .iso. Once burn is finished I try to reboot. Under BIOS, CD Drive is enabled and first. But it doesn't Boot!! Upon looking at the disc it shows 2 files; BOOTCTG.BIN and BOOTIMG.BIN. What am I doing wrong????
I need a guide to installing this OS. I understand HP warranty will be voided upon doing so. Really that is irrelevant to me. I only use this laptop for DJ prurposes Only! I just need to run my software!
