Wubi shows an error before complete installation:
Some operating systems preserves a special boot partition in it. Like Windows 7 it keeps a separate hidden boot partition in it. In such cases Wubi will crash when writing boot entry to your boot partition, beacuse wubi usually makes changes to C: drive but in Windows 7 its only installation partition not boot partition. In Windows 7 boot partition shown as System Reserved partition. To overcome this problem you have to give drive letter to boot partition for this right click on Computer then choose managein the system management window choose Disk Management (See Picture)
Then choose system reserved or system partition that has no drive letter. Right click on drive and choose Change Drive Letter and Paths. Click Add... and choose a drive letter and click OK (See Picture)
