Inspiron 15 N5010 Bootmgr is missing

Question

Hi,

Let me give a brief of the sequence before this Boot-mgr missing happened.

I had a Inspiron 15 N5010 with Windows 7 Home edition preinstalled. However after many years of proper working one day, it failed.

Service personnel found that the original hard disk crashed and a new one was installed.

However, within few weeks the new hard disk failed and that is the first time I got the message Boot-mgr missing and never the laptop was taken to service until last week.

This time I took the laptop to another service guy and he informed to buy a new hard disk, which I did again.

However, within 5 days the computer is again with the same problem of Boot-mgr missing.

One common thing, in both the new hard disk failure is that both were 500 GB hard disk and I suppose the original that came with the Laptop was lesser than 500.

The second 500GB hard disk, the service guy had partitioned into 2, but he had left the 2nd partition unformatted. But I formatted the 2nd partition and shutdown the laptop. However on powering ON today morning I got Boot-mgr missing.

Is that it has to do anything with the Huge hard disk volume or anything else?

Hi NYC10036

I did do that today morning. Initially it did an quick check and then said if you need to proceed with further diagnostics it is going to take more time. I said ok and did a thorough check. But there was nothing displayed as an error.

Let me do again and let me reply back after sometime.

Instead of going out and buying yet another hard drive, I am suspecting that the laptop's motherboard is going bad.

Run Dell Diagnostics at bootup. F12 Dell Diagnostics does not require Windows to be installed.

This is an older laptop.

I have no idea what you did or what the service engineer did. https://www.youtube.com/watch?v=oXY-dgBn1Uw

Hi,

I did a full diagnostics on startup and every step passed 100%.

I missed a point in my previous message. I had mentioned that the service engineer had not formatted a partition and the same was done by me.

But I had made that partition active once I had formatted it. Would this have caused the bootmgr have a problem?

Hi,

When the service engineer replaced an 500GB hard disk newly, he partitioned it into 2. C & D drives.

However, he did not format the D drive, he only installed Windows 7 on the C drive and gave back to me.

I went into Disk Management in control Panel and then formatted the D drive.

After formatting I clicked as highlighted in red color in the below picture.
