Hello there. I'm trying to install Win7 RC x64 (build 7100) in my desktop but not success so far. When I try to install, I get the following message: Setup was unable to create a system partition or locate an existing partition. Error: 0x80300024 My hardware involved: - a 160GB Sata HD (ST3160827AS) - a 250GB Sata HD (ST3250820AS) - a 8GB USB Stick (Kingston DataTraveler) I'm running the installation of Win7 from the USB Stick (DVD media drive not working) and I want to install Win 7 in the 160GB harddisk, which has a blank NTFS partition. The 250GB harddisk is set as GPT and has some personal files, which I don't want to lose. Obs.: I notice this topic with similiar issue where "undertow" advised to unplug the USB, but in that case the installation was not from the USB. So, don't think that's my case, right? Thanks in advance!
