Guys plz help as I download a copy of windows 7 7600.16385.090713-1255_x64fre_client_en-us_Retail_Ultimate-GRMCU.5021075.TPB and tested hash check it matched absolutely. Then I burn it from ultra iso at minimum speed. I have tried to dual boot this on my personal system having windows xp sp3 installed already. I use acronis disk director suite 10 and made another partition of 30 gb by freeing space from my drive C with NTFS file system. I tried to install windows 7 but after initialize it shows an error message that “windows failed to start. A recent hardware or software change might be the cause” and suggest given some instruction for “Repair you computer”. The infected file it shows is File :/Windows/system32/ntkrnlpa.exe and showed status 0XC0000098 stating kernel is missing or corrupt. I have Asus motherboard P5KPL-AM/PS, AMI Bios Intel core 2 Duo 2.8g, 2 gb simtronics ram, Samsung DVD Writer, 320 Gb WD HDD. My pc is only one month old. I reinstalled my windows xp and same problem. Interestingly, I’ve installed this windows 7 DVD along with xp in my office system without any problem with almost same configuration as my personal computer have.
