My friend has a Dell laptop that has a Windows 7 Home Premium 64bit on it. (Dell Win7 OEM Key sticker) His harddrive has failed, so he's got a new one & now he wants to reinstall Windows 7 but he doesnt have a Windows installation DVD (thanks Dell!!) I only have a Windows 7 Ultimate Retail (64bit & 32bit) installation disks & I know that these wont work with a OEM key. However, will a standard Win 7 Home Premium 64bit OEM disk work or will it HAVE to be a Dell one. I use a standard Win XP OEM disk to reinstall Windows all my friends/colleges laptops/PCs (as long as the PC has an OEM sticker). This works no matter what manufacture it was. But I was worried about the SLIC activation thing. Cheers guys.
