I got the boot drive from Dell and followed all the steps and I am happy to say the Dell Inspiron 3521 is up and running with Windows 8, the OS that was on it when I bought it at Walmart. I had upgraded it to 8.2 and then to Windows 10 prior to the HD failure. My wife is just going to use it for keeping her kitchen inventory and catalog as to where items are located.
My hard drive failed with error code 2000:0142 and validation code 99930. When I plugged those numbers into the matrix at Dell.com/support it said the hard drive had a hard failure and needed to be replaced. I ordered and received a new like hard drive from Dell. I called 1-877-407-4513 for help as instructed on the packing slip. I was transferred six times after waiting on hold for several minutes several times. When I was transferred for the sixth time I was assured that this was the person who could and would help me. I gave this person the same information I gave all the others and she tried to tell me that I wasn't the owner of the computer. I bought this laptop at WalMart in 2013. I no longer have the telephone number under which the computer was registered because it was a land line that we disconnected. After getting this ownership straightened out I was again put on hold for several minutes several times. When she finally came back on the phone and I told her I needed help booting up and installing Windows 10 on the new hard drive I had purchased and received from Dell. She muttered something unintelligible as she had a thick India accent and was very hard to understand. When asked if she would please repeat, she hung up on me. Had it been a dropped call she had my call back number and should have called me right back, but I received no call. I think I will go the way so many of my friends have gone and never buy a Dell computer. I want service here in America provided by Americans whose English I can understand.
